It'll be how I met Lily's dad on How I Met Your Mother. Chris Elliott has been cast as Lily's father on the CBS sitcom, a character who is supposedly something of a good-for-nothing parent. Elliott is hilarious and specializes in playing these kind of goofy roles. On Everybody Loves Raymond, for instance, his was Robert's overly familiar brother-in-law, Peter, who liked Ray just a little too much.

On HIMYM, Lily's dad will appear for the upcoming Thanksgiving episode on November 23. According to Michael Ausiello of EW.com, there will be series of flashbacks to illustrate exactly what's what with Lily and her father, why their relationship is "troubled." I'm hoping for more from this casting than Eric Braeden as Robin's dad; they never really used him right.

By the way, HIMYM should really, really bring back Marshall's parents. Bill Fagerbakke and Suzie Plakson were great in the season one Thanksgiving episode when Lily and Marshall visited his family in Minnesota, but they have never reappeared. Not even for the wedding, which was a big mistake if you ask me.

So this Thanksgiving it'll be a Lily family episode. I can't wait. Maybe he can explain why Lily can't be trusted with credit cards.
