the most inappropriate thing you've ever said/heard

[PokerBob]

i, and many of my friends, are hilarious. our hilarity, however, is often irreverant and offensive, and our wit often gets us into trouble.

my friend was going to NYU during 9/11. he was outside when the second plane hit. as they all stared in shock/awe/horror/confusion a woman said, as if thinking out loud,

"What happened to that plane? Is it in the building?"

my friend instantly responds,

"well, not without a security pass."

so, what are some of the most horrible things you have said/heard?
