the surgeon joke fails because the more likely humour would come from "well hung" which would make the joke gratuitous. Just shows "different strokes (sic) for different folks".

Like the architect that had his house made backwards, so he could watch the TV. it is a phonetic pun. You either see it or you don't. But IMNSHO is funnier than the surgeon joke.

Isn't humour deflated when you try to analyse it? Unless you are inventing a humourus piece, then the joy is in weaving a tapestry of jokettes into an hilarious guffaw. Well I try with my songs. Imagine what you can do with "My Love is Like a Chocolate Box".
