Important lesson in show business: Sometimes the little people you stepped on to get to the top will come back to haunt you.
Such is the case with Ava's (Maya Rudolph) former accompanist Walter (guest star Sean Hayes) on this week's episode of Up All Night. Ava and Reagan (Christina Applegate) run into him at the playground only to discover life has not been too kind to him since they last saw him. In a word: chaps.
Check out Sean Hayes as the saddest cowboy ever in this exclusive sneak peek at an all-new episode of Up All Night.
