I thought I knew, but I was wrong. Turns out it's Miller, not Michelob (meaning it's horse piss, rather than goat piss, IMHO). In looking into it I ended up at the Budweiser (i.e. watered-down horse piss) web site, which requires that visitors be at least 21 to enter. They verify this by asking when you were born (which, obviously, is impossible to lie about on the web...). Specifically, the question they ask is "What is your born on date?" Pathetic.
