In a hospital one day are two little boys lying on stretchers, waiting to be taken to the operating theatre.

The first boy says to the second "What are you in for?"

He replies "I'm having my tonsils out"

"Oh that's not too bad" reassures the first "they just put you to sleep, then when you wake up they give you lots of jelly and ice-cream!"

The second little boy then asks the first what he's in for. To which he replies "A circumcision."

The second boy says "I had that when I was born, I couldn't walk for a year!"
