Happy Friday, everybody! You already heard me talking at length earlier this week with Fienberg, and now it's time for Ask Alan, where I deal with three questions: TV's best guest appearance where they only appeared on the show once, my favorite use of product placement on TV, and what happened to quirky small-town dramedies like Gilmore Girls and Ed.

You can watch the video embedded either at the top or bottom of this post. And, as always, you can send questions to askalan@hitfix.com.

Alan Sepinwall has been reviewing television since the mid-'90s, first for Tony Soprano's hometown paper, The Star-Ledger, and now for HitFix. His new book, "TV (The Book)" about the 100 greatest shows of all time, is available now. He can be reached at sepinwall@hitfix.com
