Wacky British Humor

I found this site today. Even though I don't know how accurate it is, it reminds me of Overheard in New York or Overheard in the Office. My favorite one so far is this:

"May I remind all passengers that there is strictly no smoking allowed on any part of the Underground. However, if you are smoking a joint, it's only fair that you pass it round the rest of the carriage." --Overheard on the Underground
