Every sports team has "that fan" -- the guy who shows up wearing something crazy, drinks too much and acts the fool, all to the delight of the other spectators. For Utah State's Aggies, that guy is "Wild" Bill Sproat, whose antics, costumes and propensity for shirtlessness have made him something of a local legend.

In honor of Wild Bill debuting his "little teapot" costume at Wednesday night's game, we've compiled a gallery of some of our favorite looks from the portly sports-lover. After the jump, you can see video of the man in action.
