They're here: the 7-Eleven stores converted into Kwik-E Marts! The U.S. locations are New York City (42nd Street in Midtown), Chicago, Dallas, Denver, Burbank, Los Angeles and Mountain View, CA, Henderson, NV, Orlando, FL, Seattle, and Bladensburg, MD. I might not make it to the NYC store, although most of the stores will be selling some of the Simpsons related products. But alas, there will be no Duff beer.
The picture I included is pretty pathetic actually, since Comic Book Guy looks skinny compared to that guy. Here's another photo gallery of a Kwik-E Mart in Southern California. (With real live Simpsons look-a-likes! Huh?). I love the "5 Minute Parking - Violators Will Be Executed" and "Buy 3 for the price of 3" signage. Here's a short homemade video of the store in Maryland:
Who needs the Kwik-E Mart? I DOOOOOOOOOOOOOOOOO!
In another cross-promotional moment, the MLB All-Star Game commercials feature Jimmy Rollins eating a pink frosted donut after looking at "The Simpsons Movie" ad (check the video at 0:34, if you can make it past the initial shot of the giant headed Giants player).
