While were heartbroken to see Kal Penn's character Dr. Lawrence Kutner die in House, the reason for his departure was pretty epic.

Penn had chosen to join Barack Obama's administration as an Associate Director in the White House Office of Public Engagement, leading the show to have to write off his character.

After serving his time in the White House, Penn returned to acting, including taking a lead role in the short-lived but acclaimed series Sunnyside.
