1) a stripper dressed as a schoolgirl singing the Jackson Five's "ABC"
2) an aggressive drunk who gets his ass kicked by a little old lady in a wheelchair with an oxygen tank
3) a guy with an obscene tattoo on his chest who flashes a cop
4) two people in the same room talking on cell phones
5) a guy with a banana stuck in his rectum
I'm sure I'll think of more--even though I can't exactly claim originality on these; most really happened (I served in the Army with #1). Happy NaNoing!
