Kal Penn (aka Kumar, Taj, and the guy from House) was spotted by a friend at CommonWealth on Saturday night. Mr. Penn works for the White House's Office of Public Liaison and lives in the "Borderstan" neighborhood (between Dupont and Logan).
Apparently he was with a big group of people who looked like White House staff types. Maybe we'll run into him at Wonderland one day. Actually, that would probably be a bad idea, as everybody would probably just go "dude, it's Kumar! Hey, Kumar!" over and over.
