Zach Galifianakis

Why? Silly. And when he sits down in the guest chair if he could say "I am a smuggler" it would top it.


Note: This won't work as a walkout for Zach - but this reminded me of The Pepperman (if Jon Daly is on I call this.)

The Monkees - Mary Mary

Why? Song has the word Mary in it - plus that RUN DMC sampled it.
