Those of us who have been looking forward to Zach Galifianakis' guest-voice appearance on Bob's Burgers will get the ultimate TV holiday gift next month as the Hangover star lends his voice to the role of Chet in Bob's Burgers' "God Rest Ye Merry Gentle-Mannequins." Fox shared some photos from the episode, which reveal Chet and his bizarre holiday ideas, which involve the Belcher kids.

It's not entirely clear exactly who "Chet" is beyond the fact that he's a man the Belchers meet, who may or may not be living in a garage or some kind of storage facility, judging by this first photo.



And here we have Galifianakis' character using the Belcher kids to help him out with some holiday themed window displays. Here's the one for Hanukkah…



And here's the Christmas one…



Not sure what's going on here, but Chet looks pretty glum. Maybe Bob will cheer him up with a "Silent Night" burger?



Bob's Burgers' "God Rest Ye Merry Gentle-Mannequins" airs Sunday, December 16 at 8:30 p.m. on Fox.
