I will say that I've seen the beer theory on the golf course
My dad and I were golfing and a single joined us. Dude was as bad as we were, so he fit right in. He opened up his bag and started pulling out beers. We only played nine and I bet you he was on his 4th or 5th by the end. And by the end, he might as well have been Jack Nicklaus. He was playing awesome.
