I caught part of this when flipping through channels and it was quite entertaining. I hope it's on again so I can see the whole show, just wanted to mention it so you can keep an eye out for it on the Discovery channel. The pyramids would never have been built without beer, it was a form of currency back then and the builders got paid a gallon a day. People used to drink it from craddle to grave and it was considered a food source.
