The worst:
Have none of you guys experienced the horror that is Mickey's Big Mouth?
I have experienced it on many occasion and survived. One buddy and myself would go to parties with the worst beer so other people wouldn't try and bum some off us. Some notables would be Hamms, Red White and Blue, and Milwaukee's Best.
My favorite now would be a regional brew called Summit Pale Ale. But how I go through beer I couldn't afford this all the time or the others mentioned in this thread.
