Peter Gallagher and His Giant Eyebrows Will Play a Professor of Ted Mosby's on 'How I Met Your Mother'

How I Met Your Mother just keeps adding guest stars for what is likely to be the show's final season. On Tuesday, the show's Twitter account tweeted out the news that Peter Gallagher will be joining the sitcom to play a college professor of Ted Mosby's. It sounds like the group will be taking a road trip to visit Wesleyan University sometime this season.

HIMYM has already announced that Abby Elliott and Seth Green will make appearances in upcoming episodes. Most of HIMYM's younger audience would know Gallagher from his role as Sandy Cohen in The O.C. I'm guessing Gallagher won't be doing any surfing with Ted.
