Cracking up
I was reading a Slate article that cited Toby Keith and included some snippets of his song. I'm sure that you've heard his most famous hit of a couple of years ago, "Courtesy of the Red, White, and Blue"? The Slate song snippet was only of one line, which is THE most hilarious one:

..Cause we'll put a boot in your ass, it's the American way.

That is so fricking hilarious. I totally want that to become part of my lexicon, and find a way to work it into every day conversations.
