Ask a writer who they think the greatest genius of all time was and nine out ten will say "Shakespeare". The rest will make the case for themselves.
There are many strange theories about who wrote Shakespeare's plays, most of them coming from snotty London types who refuse to believe that a bloke from the midlands could have written them all.
Some claim that Christopher Marlowe faked his own death in a barroom brawl and wrote the plays using Shakespeare as a convenient front. Others make the case for Francis Bacon, Sir Walter Raleigh and others being the authors of some or all of the plays.
My personal theory is that the plays were written by two Eng. Lit. majors who went back in time, accidentally killed Shakespeare and then had to recreate his plays from memory. That would certainly explain the kegger scene in Macbeth.
One thing that cannot be argued is that Shakespeare was a lover of ale. Given the poor quality of sanitation in the 16th century, the alternative to drinking ale was drinking cholera. These Beer Philosophers: Shakespeare T-Shirts, available from CafePress, feature one of Shakespeare's more confusing pieces of dialogue: "How far that little candle throws his beams! So shines a good beer in a weary world."
Even the impossible can be found on eBay, if you are patient in your searching.
Try searching for Russian River
(you'll need to narrow down by beer name, ex. Pliny, Damnation, Temptation), Black Albert
or any of the BIG beers. Don't overlook eBay's Belgium Beer results either...
