SpongeBob SquarePants turns 10 years old this year, and is about to get a big Simpsons-style birthday bash of his own. To kick off the party, Nickelodeon is teaming up with Humanity, a cause-driven clothing line, to create a series of five limited-edition, environmentally themed T-shirts as part of a "SpongeBob and You Save the Big Blue" campaign. The shirts are "proudly made in the U.S. from 100% organic cotton, encrusted with crystals" and go for a whopping $98 a pop. SpongeBob is also getting his own fine jewelry line from Simmons Jewelry—the leading piece being a pendant encrusted with white, yellow, red, and blue diamonds, to be auctioned off at Sundance. Mr. SquarePants will even get his own prime-time documentary this summer dealing with the show's impact on popular culture. And if that's not enough, Dennis Quaid and Johnny Depp will both lend their voices to episodes this season. For the finale, Nick has planned an hour-long TV movie that will end the season with "shocking reveals." The Simpsons, of course, is celebrating its 20th birthday this year. It's good that the two shows appeal to very different audiences, or lots of yellow cartoon bits would be flying.
