The Freetail Brewing Co. of San Antonio, Texas discovered that the name of one of its beers was claimed by another company. It learned this fact when it received a threatening letter from the attorney of that company. The brewers decided that fighting the issue wasn't worth the trouble, but wanted to have a bit of fun with their response. Pictured above is a screenshot of part of the letter, which can be found at the link. Much to Metzger's credit, even though he didn't go to law school, he knew about the advantage of sending a copy to the Flying Spaghetti Monster.
