This malt liquor advantage is old news.

Was a personal tradition to push back from my desk, put up my worn Tony Lamas and pop the top on a robust can of Schlitz ML half way through each senior year college final exam. The head of the engineering dept. use to just shake his head and laugh. One not so lithe lit prof got quite flustered. Got to be interesting if there was a few on the same day. Obviously, A's were a given....
