There is a hilarious clip of Jack Black on "iCarly" released ahead of his guest-starring episode. Black, who co-starred with Miranda Cosgrove on "The School of Rock", is playing Aspartamay aka Spencer's online gaming nemesis who challenges him into a war of words.

"Everybody was really excited to get to work with him," Cosgrove said. "Jerry Trainor reminds me of Jack Black - they're both so funny - and it was really cool to see them work together. I loved seeing them sing a song in the episode. They both dress up as their favorite characters in this World of Warlords game."

The episode is called "iStart a Fan War" and it airs November 19 on Nickelodeon. Also in the episode, Carly, Sam, and Freddie accidentally start a fan war between who should end up together, Carly and Freddie (Creddie)? or Sam and Freddie (Seddie)? A clip where Carly, Sam and Freddie attend the WebiCon is also shared, along with a clip of Carly denying that Freddie and her are a 'thing'.
