Dude,

The beer is fattening.

She doesn't want grandmother arms and a pouch when she's out with Mr. Skinny Hotpants Guy.

And...from what I hear, anthropological studies have shown that out in the great American Heartland, the natives offer beer as some kind of a love offering. You know...Kris likes Swen, Kris gets Swen a beer -- look, I'm into cosmos and man-wiches, so don't ask me what these yahoos do out where you live.
