Rick Ca-Rolled

My bar was caroled last night. The six of them came in and sang "Rudolph the Red-Nosed Reindeer" to our crowd. Pretty much the entire bar sang along, including Scroogy McGenius. I remarked that this was the best trick I'd seen yet for getting free drinks, but then they left without having anything! What a wasted opportunity to get wasted on the cheap. Sing a couple carols, tell the bartender you'll keep singing until he pours you a free shot, down it, and move on to the next victim, er, bar.
