The coolest thing about Magic Hat beer (besides the fact that it is great beer) is that if you drink enough of it and if you are lucky enough, you will eventually find a cap that has a phone number printed on it and a message saying that you are a winner. When you call the phone number on the cap, they tell you to flatten the cap with a hammer (this is fun) and send it to them along with your address and they will send you a free shirt. Very cool.
The least cool thing about Magic Hat beer (besides the fact that it is not free) is that if you find one of the winning caps, flatten it out with a hammer, and send it in with an index card with your address on it, they don't send you anything in return! The nice voice on the machine that answered the number printed under the cap told me that I would get my free shirt by mail within 8 weeks. Well, it has been two years and no shirt!
Their beer is good enough, however, that I continue to drink it even though I have been bamboozled.
Their stout is called Humble Patience, by the way.
