Broadcasters might have to help me out with this one, but it seems like drinking in the booth during a game is a frowned-upon practice. Pat Foley seems to have made an exception to this rule and the results were quite hilarious.
During the first intermission of the Blackhawks game against the St. Louis Blues, the Chicago play-by-play man decided to pay tribute to the late Harry Caray. Of course, this included ridiculously huge glasses and a cup of beer. And I think after watching his goofy toast, it's safe to assume that wasn't exactly his first cup.
