Ok, maybe I'm a bit young but I never remembered Coors being referred to as "The Banquet Beer." Now all I see are commercials about how "Back when men got together...they called it a Banquet...and they'd drink the banquet beer...Coors Original (pronounced "coo-ORS").
To me, this translates to "Yeah, ok, our beer kinda sucks, but c'mon, man the fuck up and drink it just like the tough rugged guys back in the day when they would go to...banquets." Regardless, I love the commercials. Here's a funny spoof worth watching.
