A self–proclaimed fratstar, Dave Dobkin leads a double life — he is both the AEPi president and the infamous Penn mascot: the fightin' Quaker. But when he's not pumping up fans with his 18th century pervert impressions, you can catch him rocking out to girly music or fratting it up — in a sweater, of course.

Street: What qualities does it take to be the Penn mascot? Dave Dobkin: To begin, even though the mascot wears a giant head, you still need to be really really ridiculously good looking to even get a tryout. Second, the magical power to change spontaneously in nooks and crevices — or behind a tree. Finally, incredible miming techniques. You’d be surprised what kind of conversations you can have without words.

Street: The Quaker doesn’t talk, but if he could, he’d say… DD: To any girl between the ages of 18 and 80, can I have your numba? Can I have ittt?

Street: Write us your six word autobiography. DD: Gregarious mascot, hairy man, frat, Phan. Child of Simsbury, Man of Penn.

Street: There are two types of Penn students… DD: Those who have a dormant Twitter account and those who tweet. Those who have no idea where the AEPi chapter house is and those in SDT. Those who’ve high–fived the Quaker and those who missed the first football game freshman year. Those who call it Cohen and those who call it Logan. Those who enjoy the writing on the stall and those who are afraid of the bathrooms on campus.

Street: My PennCard looks like I’m… DD: You mean PennCards — I have one for the Quaker and one for me. The Quaker’s looks like a colonial pedophile, and mine looks like a dorky pre–frat high school senior.

Street: Which of your jobs is harder: AEPi president or UPenn Mascot? DD: Tossup! Dealing with overprotective Jewish mothers or dealing with crying children (yes, the Quaker is creepy and scares kids often).

Street: What do you wear under your mascot suit? DD: You’ll just have to meet me under the bleachers to find out.

Street: When I’m not in my Quaker costume, you can find me… DD: Aggressively air guitaring with Kweder and Mark, hanging out with hipster city planning students and making Katy Perry remix videos.

Street: You’re this week’s ego, but who’s your alter–ego? DD: It would be too easy to say the Quaker. But I’d have to go with Bob Dobbs, CEO/President of Bob Dobbs and Associates.

Street: What’s the frattiest thing you’ve ever done? DD: I would have to say meeting Guster in the quad during Fling and making it on their tour blog thereafter.

Street: What will you miss the most about Penn? DD: The creperie guys, Louis of Einstein Bagels and Sweaterbrunch — yes, brunch every Sunday morning… in sweaters, with four of the finest gentlemen (Hi Nate, Kyle, Josh and Ethy!).

Street: Ever heard of totalfratmove.com? Make up your own TFM. DD: Woke up after formal with a wet and dysfunctional Blackberry. TFM.

Street: What’s the weirdest dream you’ve ever had? DD: Well to me this is normal, but I once had a dream that the man behind the Phanatic went missing and I was chosen to fill the role for the day… they say dreams become reality!
