Words & Slang, kinda like Bangers & Mashers

I love to learn the stories of slang words and slang expressions.  Things like "caught red handed", "lock, stock, and barrel", "balls to the wall", and "freeze the balls off of a brass monkey".  Btw, none of these are "dirty" and are perfectly fine in mixed company if you know where they came from.  I friend (Hi Bill!) sent me a link for "Bob's Your Uncle, Lame Duck, Malarkey, Dressed to the Nines, MindYour P's and Q's, and Uxorious".  Enjoy!  I sure did.
