You can go to This is Why You're Fat. My friend Jon brought my attention to it yesterday and it was also in Grub Street. In case the title of the blog is not self-explanatory, allow me to give you a pictorial excerpt from the blog:
Corn Dog Pizza
Mega Double Stuff Oreo
The Nacho Burger
Okay, am I the only one who didn't realize this site existed? I don't think I can frequent it but it makes me feel better that I have eaten a whole carrot cake in one night.
