I spelled hilarious wrong on purpose.
This is a t-shirt titled "I Scream" from Threadless.com. I don't really know anything about this website and am ready to go read a book so I'll let you look if you're interested, but a friend had it on her gchat and I thought it was hilsarious.
The artist is Brock Davis and the t-shirt is available in baby onesies as well as adult sizes. It's just so witty. I don't wear t-shirts very often, but if I had a baby, I sure would buy it for him/her. It's not cynical is it?
