Now we know which Springfield truly rules them all [0]: Springfield, Vt.! The small town got 15,000 votes in USA Today's Springfields poll [1] and will get to host The Simpsons Movie [1]'s July 21 premiere.
The town of 9,300 apparently was too small to be invited into participate in the contest [2] at first and only got involved after seeing a news report and asking to be included. But their video — which featured a Homer-like character chasing a giant, pink-frosted donut past town landmarks — edged out larger, relatively more famous Springfields to score the premiere. Illinois came in second, with Oregon not far behind in third. Poor Florida didn't do so well, languishing in 14th place.
Nearly 110,000 people voted in the contest overall, and of course, Vermont's win is likely to draw some ire from supporters of the other Springfields. To them, Vermont Gov. Jim Douglas had just one thing to say: "Don't have a cow, man."
