I ran a search for "Tribe" and checked every result, but didn't find this anywhere...
I found a
Lemmings Tribe Test.
I took it, and apparently,
the Classic Tribe is my best match.

Just wondering if anyone else has tried it, and what you got?
Beach lemming, apparently. Can't say I expected that.
Prob Lem, how do you always find Lemmings related things/oddities like this?

I am a Classic lemming, too. Though my favourite colour is blue instead of brown..
So this time I'm an
Egyptian lemming apparently. It says "But Sciences like math [...] aren't your forte.", so I'm not quite sold on this classification.
I think I took this one quite a while back two or three times, and one time I got Egyptian too. It's kinda random by itself but even more so if half of the movie etc. references I don't even know.
You are an EGYPTIAN Lemming!
You're an intellectual. You like to read, maybe draw, and maybe you like history. But Sciences like math and biology aren't your forte.
Um, no?

EPIC FAIL for me accuracy-wise. But the answers are entertaining I'll give you that.

I'm gonna try and see what happens if I picked all the jokey-est answers.
[edit: but then again, how can the result be taken seriously with phrases like "Sciences like math"? Um, math isn't a science, hello......

]
I kind of see where they're coming from. Math is kind of like non-applied science, if you think about it. (Though I may be slightly biased here, since I'm far more knowledgable about physics and chemistry than, say, biology.)
I tried the case of picking the psychopathic answers (eg. often 2nd-to-last). Apparently the author of the quiz really hates the Polar tribe?

You are a POLAR Lemming!
To put it bluntly, you're an asshole. You make a hobby out of scaring children, kicking puppies, shaving cats into stupid poodle getups, and stomping flowers. Either that, or you clicked all the mean answers because you thought they were funny, which I guess means you have at least some kind of mean streak.
I dunno, I suppose it's better than using Highland as the scapegoat if one tribe has to be sacrificed for the evil side?
You'd think Shadow tribe would be the evil one...

Well, not quite. Maths isn't really about observing things from reality and building frameworks/theories that describe those things and that can be falsified.
Maths is more about building models that might (applied) or might not (non-applied) be useful for working with those scientific frameworks, but either way there's no falsification, it's a model with axioms that you can choose to accept or not, but there's no right or wrong in your choice of axioms, just a more or less useful.
I'm a beach bum.
And you got that in the test, too?
I got EGYPTIAN.
"You're an intellectual. You like to read, maybe draw, and maybe you like history. But Sciences like math and biology aren't your forte."
What?

I don't really like to read (unless it's the lemmings forums), I don't like history, and I'm good at math and some sciences, but, like many people are stating, math isn't a science. Definitely not me. But, I guess with a limited number of answers on every question, it's hard to get somebody's personality in only twenty completely random questions. And a lot of the questions I didn't really like any of the answers.
I'm a beach bum.
And you got that in the test, too? 
Yep, the test gave me beach tribe.
I tried for again hoping for a better result than beach bum, though, and got this:
You maintain a balance between physical and mental strength. You're athletic, though not as strong as a Cavelem, but you're also not as thick as one. You're intelligent, but not as smart as an Egyptian or Space lemming, but also not as puny. At least the cute girls won't want to "just be friends."
I'll settle for that. I don't know if I want the
Lemme Fatale after me, though.
And a lot of the questions I didn't really like any of the answers.
That's the worst feeling when writing a test, personality or otherwise. :/
Medieval
We had a topic about this quiz on the old (still inaccessible) forum. IIRC I ended up with Space?
I got Egyptian this time. I guess I had it coming since I made all my L2 and L3 levels in Egyptian styles
I'm a Polar Lemming, which means, to put it bluntly, I'm an asshole.

I've been described as making a hobby out of scaring children, kicking puppies, shaving cats into stupid poodle getups, and stomping flowers, all these things that I never do in real life. What a stupid quiz, especially for the heavy-hearted like me! At least it's just for fun.
And I did pick random answers after allSpeaking of stupid, As a Brit I never heard of guys such as Jason Vorhees, Bob Dole, Jimmy Dean, etc. let alone anyone else outside the US.
Apparently I'm OUTDOORS TRIBE
You're the outdoorsy type. You like gardening and talking to your plants, and think cars are the work of the devil. Your wish is to live in a shack in the woods. I'd say you already do, but then you wouldn't have a computer to be taking this test with, now would you?
tbh I didn't know what half the questions were about hehe "Eternal Darkness"? "Bob Dole"? "$.50"? (probably all really famous in USA)
Here's all the descriptions (spoilers to some random personality quiz I guess)
CLASSIC - There's nothing special about you. Your name is probably Bob, and your favorite color is brown. Maybe you can curl your tongue. Maybe.
CIRCUS - You got here by either clicking all the goofy answers on purpose, or managing to rack in enough Circus points. If the former, cute, but now maybe you should go back and answer seriously, or as seriously as you can. If the latter... well, I don't know what to say.
CAVELEM - You are strong and athletic, but you're not the brightest crayon in the box, the fastest gun in the west, nor the sharpest hunk of cheese... mmm, cheese.
SHADOW - You're an introvert, preferring to keep to yourself. You might just be shy, trying to fit in only to embarass yourself. Or you might be all-out antisocial, and wish everyone else in the world would just drop dead so you could have the place to yourself.
SPACE - Stand back! You know regular expressions! You are going to try SCIENCE! It works bitches. You're not slacking, your code's compiling. Oh, and you're probably a fan of XKCD.
OUTDOOR - You're the outdoorsy type. You like gardening and talking to your plants, and think cars are the work of the devil. Your wish is to live in a shack in the woods. I'd say you already do, but then you wouldn't have a computer to be taking this test with, now would you?
BEACH - You are laid back and easy going, and your idea of a perfect afternoon is downing some hot dogs and napping for three hours, then downing a hamburger or two when you wake up. If somebody walked up to you and called you ugly as a baboon and dumb as one too, you'd thank them and carry on your way. Work and thinking might hurt your head, and under your bed one might find moldy food, old socks, banana peels, and dust bunnies.
SPORTS - You maintain a balance between physical and mental strength. You're athletic, though not as strong as a Cavelem, but you're also not as thick as one. You're intelligent, but not as smart as an Egyptian or Space lemming, but also not as puny. At least the cute girls won't want to "just be friends."
EGYPTIAN - You're an intellectual. You like to read, maybe draw, and maybe you like history. But Sciences like math and biology aren't your forte.
HIGHLAND - You're a party animal. You probably hold/held or attend(ed) a lot of college drinking parties. You probably woke up one morning with a headache, a lampshade on your head, and stripped to your underoos. Nobody will ever know what happened that night, and nobody wants to know.
POLAR - To put it bluntly, you're an asshole. You make a hobby out of scaring children, kicking puppies, shaving cats into stupid poodle getups, and stomping flowers. Either that, or you clicked all the mean answers because you thought they were funny, which I guess means you have at least some kind of mean streak.
MEDIEVAL - You're a fan of the old ways, a patron of the old ways, or just old. So old you think bell bottoms are all the rage, disco is in, and Marmaduke is funny. Okay, that was low, anyone old enough to think Marmaduke is funny probably threw their computer out the first time it performed an illegal operation.
