My favorite is the one where he pretends he is a robot.
I love the how to be English videos and how to speak English. but all of them are amazing!

My favorite is "Doctor What" at least I think that's what it's called... =|
My favorite is definitely Understanding Teenage Boys. I die of laughter everytime I see it.
I like Too Many Questions
I love a lot of his videos, but there are a few that hold special places in my heart.
My American Accent, because it was the first one I ever saw.
Never From Concentrate (With Bits) because it cracks me up. I find that one to be hilarious.
Time To Reply. His eyes are fun to stare into during that one.
