Hymen on toast
Several years ago my friend Ash made the mistake of asking myself and two female friends something along the lines of "what actually IS the hymen anyway?"
Oooooh dear.

We proceeded to convince him that it was a type of mustard, traditionally given to girls by their fathers dating from pre-medieval times.
"Oh wow, really?" Said Ash. "Then ... why does it mean it gets broken if you lose your virginity?"
Frantically inventing, we told him that the fathers presented the symbolic virginity-mustard in a sealed glass container, and that when the girl got married, it was broken open and she was anointed with the mustard on her wrists and ankles.
"Whoah ... that's really interesting. I wonder why it died out," said Ash.
I think it was around then we fell over laughing and actually told the poor sod what it was ...
