Why Rats Don't Have Beer Bellies

Why Don't Rats Have Beer Bellies?

Because they don't drink beer! Duh.

I know a lot of research relies on lab rats, but sometimes it just seems so, please excuse me, retarded. "Let's see... I wonder why human beings get fat when they drink and eat too much... Hey! Why aren't all these rats fat? Let's feed 'em some beer and see what happens." Sounds a little too much like a bunch of bored frat boys, fuckin' with the house dog. Hey, better living through science, no?
