Here’s a Classic, and sorry if someone already posted it.
a story from many many years ago, but still a good one.
Jewish Guy goes skiing with his date, and they get stuck on the ski lift and it begins to get dark. Because of (the) yichud (monster), the guy jumps off and breaks his leg.
Ouch! Well at least he escaped an issur!
[a) what happened to that couple? no clue. b) what happpened to the girl? no clue.]
