'Big Bang Theory' star Jim Parsons is traveling across the space-time continuum networks for a guest role on Nickelodeon's 'iCarly.'
According Entertainment Weekly, Parsons will play a psychiatric patient who believes he's from the future. The Emmy winner's character, Caleb, befriends Carly (Miranda Cosgrove) and her friends when they visit the psych ward he calls home.
Jane Lynch and Jack Black have recently popped up in guest spots on the hit Nickelodeon series.
Look for the episode featuring Parsons to air later this year as part of Season 4. In addition to his 'iCarly' gig, Parsons is appearing on Broadway in 'The Normal Heart' and will also be returning to 'The Big Bang Theory' on CBS this fall.
