Looks like Kal Penn, how is having himself one hell of a year, will be joining the cast of Fox's House next season: 'House' gets a new group of trainees. He's part of a group being brought in after the resignations of Dr. House's underlings last season. No specific information on Kal's character quite just yet, but he will no doubt suffer quite a bit of verbal abuse from the caustic title character. Between this, The Namesake, and the upcoming Harold and Kumar sequel, this guy's career is riding pretty high.
