'HIMYM' exclusive: Look who's been cast as Lily's dad!

At long last the mother father is revealed!

Sources confirm to me exclusively that comic goofball Chris Elliott has landed the pivotal role of Lily’s estranged dad on How I Met Your Mother.

The highly-anticipated family reunion is slated to air Nov. 23 when father and daughter come face-to-face at a Thanksgiving celebration hosted by Lily’s grandparents.

I’m told the episode will feature childhood flashbacks that will shed light on Lily’s very troubled relationship with her father. Word is the dude was a big-time loser/crook, which makes Elliott’s casting pretty perfect if you ask me.

You agree? Sound off in the comments!
