Back before it politically incorrect to make such jokes... Well I can't say that. I'm no longer an adolescent male so maybe the jokes are still being made but not around an "old folk" like me.
As I was saying, back then there were lots of jokes about "merit badges" being given for things like that. Merit badges for 'carpet clean' and other bad puns that were as close to innuendo as we could get. The only one I remember completely is the class:
Q) when does a Beaver graduate to the Boy Scouts?
A) when he eats his first Brownie
And no, the others I half remember weren't any better than that. But typing that out brings back memories of a bunch of little boys telling dirty jokes to each and laughing while secretly hoping that someone would explain why the jokes were funny. |
