My personal fave dates back to the mid/late 80s and hinged on a US/UK language-divide gag, in which a worldly high-school girl (in shocking pink tights, I recall) attempted to seduce a JW classmate, who hightailed it home and related the whole episode to his mother, with words to the effect that "a worldly girl at school got me into an empty classroom (like she had a gun at his head, LOL) and tried to get me to commit fornication with her!!"
At which point the anguished mother cried "OH, RANDY!!" (the boy's name)
Now, for any North Americans who may be in the dark:
randy (UK) = horny (US)
As you can imagine, at that a ripple of snorting and choking rippled around the stadium I was at, along with, I imagine, every other convention venue in the UK. I'd love to have been at a big international (like Twickenham) just to see the puzzled looks of any visiting American dubs as the suppressed hysteria erupted around them.
The GB obviously never did their linguistic/cultural homework for that one
