The Bro Code means never quitting on your bros … but that’s what Kalpen Modi (aka Kal Penn) just did. Again.

Perhaps all the negativity and polemics of the past few months got to be too much for Modi, because last week news broke that he will leave his position as assistant director of the White House Office of Public Engagement to pick up his acting career right where he left off.

This was less-than-surprising because when Modi spoke at the Campus Progress conference in early July, he chatted about the importance of public service to the group of young politically active progressives while also speaking about his frustration with working in politics.

He said his most rewarding moments at the White House transcended politics. Paradoxically, the constant struggle to find common ground among groups with disparate ideologies and to get them to work together seemed to wear on him.

He also voiced frustration that people “sort of lose a certain amount of credibility when we become staffers.”

Modi will join the cast of the hit CBS show “How I Met Your Mother” — at least temporarily. He will play the love interest to Robin (Cobie Smulders).

Modi joined the White House in 2009, left in 2010 to film “A Very Harold & Kumar Christmas,” and then returned.

“There was a writers strike on at the time, so it’s not like I could work anyway,” he quipped.

“Try not to call each other crazy,” he advised the group.
