Don't know if it's a bit late in the discussion for this (couldn't be bothered to read up
,) but I have made some pretty "crude" remarks which I (and my friends), thought were very funny.
My favourite one was this one:
This happened several years ago, we were watching a football game and one of my friend's girlfriends (who is quite a football fanatic), was really stressing out the entire time, yelling, cussing, screaming, quite annoying. So, after the game ended, she gets a phone call, her granfather had had a heart attack (and later died because of that). So, I say "Oh, he watched the game as well?", and everybody cracked up.
