Is there anything more extreme than skateboarding out of a helicopter? "Dinosaur Comics" does not think so, which is why it has released a new tee called "The Most Extreme Shirt" through Topatoco. Personally, I think that commercial where the guy falls out of the sky in a shopping cart, lands on a highway, and then drives against traffic down the narrow column between two tractor trailer trucks while stretching his arms out like Kate Winslet may offer some competition in that department, but since that's selling deodorant and not a shirt this is still your best bet for all of your extreme clothing needs.
