We don't know Yoo-hoo in their right mind would drink two-and-a-half gallons of chocolate milk in one shot, especially after watching this poor sap.

A fella by the name of Pat Bertoletti admits the stunt (warning: the video is slightly NSFW) is stupid, but, like going on a blind date or paying for a Jennifer Aniston movie, he does it, even though he knows the results won't be pretty.

Poor Mr. Bertoletti (which, our research shows come from the Italian root for the word "moronic eating habits). We do like his Montreal Expos shirt, though. Much like his toned muscles and washboard abs after drinking too much chocolate milk, they no longer exist.
