On the November 23 episode of How I Met Your Mother, we'll meet Lily's dad Mickey, played by Chris Elliott.
But that's not the only relative celebrating Thanksgiving with viewers, as the show will take fans inside Lily's grandparents' home. Once there, we'll learn that Mickey’s antics have led to grandma breaking her hip and losing her retirement fund.
Also, according to TV Guide Magazine, the sitcom will flashback to to an 11-year-old Lily, as we learn what sort of influence her shady dad had on her.
Viewers should also prepare to be taken back to Lily’s wedding day, which featured a revolting interaction between Mickey and Lily's best friend, Sandy.
