Money Thief is a slick flash game in which you go around being a jerk. All parties involved are adorable, though, so it's okay. It was designed for Ludum Dare 18; here's creator zachwlewis' description:
"To compound the matter twofold, your marks become the ultimate weapon of money-getbackery whenever they get thieved! It turns out, the money (root of all evil, et cetera) you've stolen is the TRUE enemy, turning those without it into crazy people, hellbent on retrieving what was once theirs!"
"Also, YOU GET TO JUMP AROUND, CLIMB ON THINGS AND STEAL SHIT."
I implore you to read the updates as well. They're just as good, if not better.
