Greta Van Susteren and Tucker Carlson have a knock down, drag out, hair pulling, slap fight over Sarah Palin. Don't forget your popcorn!

Van Sustern: You're a liar!

Carlson: No I'm not!

Van Susteren: Yes you are!

Carlson: Am not! Am not! Am not!

I think I will play this over an over today whenever I am feeling a little down. It cannot fail to put a huge smile on my face.
