Here's another, its a little rusty but I can smooth it out mebbe if people like it:
Lemmings
The joy of watching lemmings tumble
Across a temple\s twisted stair
Or amongst the stripy circus poles
With leaf-green tumbling hair.
When they call [let\s go\ from their downwards door
They really mean their call
For drowns and crushes and roasting flame
Awaits their happy fall.
At your command they\d dig a hole
Or build bridges over black, black chasms
Or tunnel through a random wall
And hope your reflex does not spasm.
Their trust in you is absolute
And mindlessly they stride
Towards a doom you would avert
Had not your patience disinclined.
They drop and die in soggy rhythm
To the happy tune that keeps them sane
When they are vanquished you restart the level
and make the same mistakes again.
When finally you have cleared safe a path
Across a metal hell
They\ll thank you with their cry [yippee!\
And leap to sunny, leafy dells
Next time you see a green-blue spill
Or hear a [let\s go\ sound effect
And you see the need to have some killed
Kill them with respect.
Hope you like it!!!
