During the 2004 Summer Olympic Games, a bunch of guys in D.C., after spitting up their beers, wondered why Puerto Rico has an Olympic team (which beat the U.S. in basketball).  Probably some more beers later and voila, the District of Columbia Olympic Committee.  According to this Washington Post article, they are focussing their efforts on building a competitive curling team (ok, tongue in cheek, they can't even practice curling in D.C. but have to go to Laurel, MD).
