\'The Simpsons\' give fans a preview of their special LEGO-themed episode

The Simpsons have released a trailer for their special, LEGO-themed episode. The upcoming special marks the 550th episode of the series, and is titled "Brick Like Me." Homer, Marge and the rest of Springfield wake up in the episode to find their town has been LEGO-fied. "We've literally been at this [episode] for two years," executive producer Matt Selman recently told TV Guide. "It's been an epic process." "The LEGO brand is all about creativity and imagination," licensing and entertainment vice-president Jill Wilfert added. "This was a chance for us to be a little bit edgier than we might normally be." LEGO has released special Simpsons figurines to mark the occasion. The LEGOs went on sale Thursday, and cost $3.99 each. "Brick Like Me" airs this Sunday, May 4 at 8 p.m. ET on Fox.
