You have quite an extended streaking scene. You do any gluteal workouts in preparation?

I did nothing. When you have certain physical gifts, I think you should share them. I’ve gotten a lot of mileage out of this body.

How many takes did you do?

We were out there a good couple of hours. The street they chose to do it on had these storefronts. All of them were closed for the night except this 24-hour fitness place, and all the treadmills were up against the window. People started pointing, waving, saying, “Oh, that’s that guy from ‘Saturday Night Live’!” I’m in a robe until the final moment. Then I drop the robe and I hear “OH, MY GOD!” through the plate glass. By the third take, no one was on the treadmills.

How did playing George W. Bush on “SNL” help you in playing a fraternity guy?

When I played Bush, I just imagined a fraternity guy trying to be president. I had to develop more interpersonal skills to play the frat guy.

When you decided to pursue acting, did your parents want a refund on their tuition money?

They’ve always been supersupportive. My dad’s a musician and an entertainer, so we kind of had the talk where I said, “I’m thinking about doing this.”

This isn’t the birds-and-the-bees talk.

Yes. I never realized how babies are made. It was really awkward.
