I love his time time travel video. Its great.
My favorite is the one where he pretends he is a robot.
One of my favorites is the one where he talks about time travel with the cookies.
I LOVE the Alex and Charlie format XD They should make more of them!!!
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.
I love his "Wall Of Stuff" video. I honestly quote it all the time. xD
For some reason I love Long Hair, I think it's amazing, funny and Alex is in it! So yeah my favourite one is long hair and if you haven't seen it check it out
My favorite Charlie videos would definitely have to be the Challenge Charlie Balloon Animals video and the Cooking with Charlie Brownies.
They contain the perfect combo of scripted and unscripted humor.
Oh, and his music video for Ben Fold's Saskia Hamilton is pure genius.
