Fair to moderate? HIMYM-style

Tomorrow night I'll be moderating a Q&A session with most of the cast (minus Jason Segel) and several of the producers of "How I Met Your Mother." Unlike the Paley Center thing a couple of weeks ago, this one's not open to the general public -- it's for television Academy members only, as part of the show's Emmy campaign -- but I wanted to open the floor for any suggestions about what questions you might have for the cast or creative team. The episode being screened immediately before the panel is "How I Met Everyone Else," which was season three's creative high point.
