We've had Kevin Roose guest blogging this week. If you missed it, he taught us 5 Rules From His Semester at America's Holiest University, 5 Things He Learned By Being the World's Worst Evangelist, 8 Things You Didn't Know About Jerry Falwell, and he also popped a quiz based on Liberty University's exams.

Today we have four copies of Kevin's book to give away. If you think The Unlikely Disciple: A Sinner's Semester at America's Holiest University would look good on your bookshelf, read on to find out how you can win. We're going to give the first of our four copies to loyal reader/commenter Witty Nickname. His wife is expecting, and while this might be a strange choice for a baby shower, we really wanted to make sure our gift was not a duplicate.

You need not expand your family to earn one of the three remaining copies. Since Kevin's book is about the semester he spent at Liberty University, we want you to pitch us your idea for an ethnography. Where will you go? With whom will you live, observe and write about? Why should we care? The three most interesting pitches, as declared by our esteemed panel of judges, will be awarded with the book. We look forward to reading your entries. Good luck!
