the “two nuns in a bath” joke
I puzzled over this one for a while and got nowhere; so I looked up the explanation at some website or other. My problem is that when I learned English as a small child, I was taught to pronounce the “H” in words like WHEN and WHAT, and still do, even in my head (e.g. when reading).
The joke’s hardly worth explaining anyway........ if it weren’t off-colour, as well as terminally feeble, it might perhaps barely have made it to the bottom margin of an inside page of Comic Cuts; I doubt if Beano or Dandy would have touched it.
