Garrett Dillahunt is barefoot quite often (either completely or in flipflops or in socks) in the sitcom Raising Hope (Season 1 DVD out now). Lucas Neff, who plays his adult son, has several sock appearances in the first season, but shows off his feet in the season finale.
If you haven't seen the show, it's hilarious and outrageous at times (the basic premise: Dillahunt and wife Martha Plimpton got pregnant as teens and now their 23 yr old son Jimmy(Neff) has fathered a baby with a girl who turns out to be a serial killer. She's executed in the pilot so he takes custody of the baby. Throw in Cloris Leachman as their senile great-grandmother and dysfunctional family hijinks ensue...).
Funniest scene? Burt (Dillahunt), after getting a pregnancy scare, decides to get a vasectomy. He asks Jimmy (Neff) to accompany him to the doctor for the procedure. For some reason, he did not shave his private area for the procedure and Jimmy winds up doing the shaving. If that isn't bad enough, Burt is looped out on sedatives and suggests that he'll return to the favor for his son if Jimmy is willing. The look of amazement and disgust on Neff's face is gutbusting.
Close second: the Halloween episode in which Maw Maw (Leachman) thinks she's a nine year old girl and goes trick-or-treating dressed up as a cat.
