Remember what it was like to be 21? No? Us neither. However we imagine Kevin Roose will clearly remember the book party thrown last night for his debut The Unlikely Disciple, which is about the semester he spent at the Reverend Jerry Falwell's Liberty University, a conservative Baptist school in Lynchburg, Virginia.

Roose, who is currently 21, told us he was headed back to Brown as soon as the party was over so he could write his biology(?) exam about the krebs cycle today. That's dedication!

Roose got his start (if that phrase can be properly applied to a 21 year old published author) as an intern for A.J. Jacobs (who co-hosted the party along with Scott Poulson-Bryant) whilst Jacobs was penning The Year of Living Biblically -- for those of you not in the know the book recounts Jacobs' attempt to follow all the rules in the Bible for one year. Roose told us that apart from it being an amazing opportunity, the strangest part of his internship was when Jacobs was unable to shake his hand due the rule (we are paraphrasing here) the says men can't touch other men who have spilled their seed on themselves. So there you have it. A few more pics (courtesy of R. Sklar) after the jump.
