Heh, got so bored that you actually filled the whole piece of paper? Awesome! :-D
I once drew the attached card for a game of 1000 Blank White Cards. It's a parody on Magic the Gathering where there are blank cards in the pile among older, already drawn cards. If you get a blank one, you can draw anything on it during game play and use it later. Google or Wikipedia know more. ;-)
The German text on the card translates to: "Well, almost, right? - The card you're playing will only count as... ALMOST beging played... - Play this card anytime!" Thus, it makes a player discard his card during his turn instead of playing it from his hand.
