'How I Met Your Mother' Creators Share 6 Plans for the (Possibly Final) Season 8

Radnor, who filmed his university-set indie Liberal Arts at his alma mater Kenyon College in Ohio, took a trip down memory lane in the latest episode of MTVu web series When I Was in College. Sitting in the auditorium at New York University's Tisch School of the Arts where Radnor had attended grad school, the actor revealed his greatest college experiences in an exclusive video to The Hollywood Reporter.

For Radnor, coming back to NYU was like deja vu -- and the familiar surroundings certainly helped bring a wave of nostalgia.

"Is Pizza Mercato still around the corner?" he asked. "We were there all the time. It was $3 for two slices of cheese pizza and a small drink. I am embarrassed to say how much I had Pizza Mercato, the $3 special."

Liberal Arts, which Radnor directed, wrote and stars in, centers on a 35-year-old (Radnor) who has a fling with a college student (Elizabeth Olsen). While his real-life college years did not mirror those played out on the big screen, Radnor took part in a fair share of questionable activities.

"There were two guys down the hall from me who had the party room," he recalled. "There was so much drinking in that room. We were in the room one time and there was this jar of liquid. [One of the guys] wouldn't get up in the morning, he would just pee in the jar and he just left it."
