Charlie Day And Fallon Play 'Long Pour' Beer Challenge (VIDEO)

Charlie Day, most famous for his odd man-child character Charlie on "It's Always Sunny in Philadelphia," stopped by "Late Night with Jimmy Fallon" on Tuesday to promote his new movie "Horrible Bosses." While there, he and Fallon played "Long Pour," one of the show's more entertaining guest challenges, and one that was perfectly suited to Day's bar employee character on "Always Sunny."

In the game, which Fallon had previously played with Ed Helms and Jason Sudeikis, the two men are forced to pour beer from bottles into mugs, and then mugs into a respective beaker -- all while their arms are kept horizontal by tying their wrists to a broomstick behind their back, forcing the beer to be transferred through a series of "long pours." (Get it?)

Inevitably, not all the beer makes it into the mug or the beaker, but it's strangely fun to watch the two men try. We were particularly impressed with one of the men's ability to pour, but you'll have to watch to find out who wins.
