If this is going to be a Christian nation that doesn't help the poor, either we have to pretend that Jesus was just as selfish as we are, or we've got to acknowledge that He commanded us to love the poor and serve the needy without condition, and then admit that we just don't want to do it.

- Stephen Colbert.

-Spit and Image, Spitting Image, Split and Image, Splitting Image ..... I don't know which one was original anymore!
-Butt Naked (Buck-Naked)
"I could care less" (I couldn't care less)

Great question! I know there are others that make me cringe when I hear them!
