Years ago I did some work in a special school. At end of lesson we had 10 mins to kill. Had a quiz. One of questions was.. "What is Queens surname?".. General look of bewilderment. Then a little lad put his hand up and blurted out in excitement..
"Vagina"..
Funny thing was nobody in class reacted at all... Not a stifled laugh or anything...
I asked why he thought vagina.
His answer.
"You've heard people say Elizabeth vagina haven't you sir"...
"Well, actually no, but I see your thinking Michael."!
