Bob's Burgers S03E09 - God Rest Ye Merry Gentle-Mannequins
Bob inherits a storage unit, and the whole family imagines it's filled with treasures. Instead, they find a man named Chet (guest star Zach Galifianakis) living inside. Linda, feeling the holiday spirit, persuades Bob to invite Chet to stay at the restaurant. It's discovered that this stranger, who claims he was once a mannequin, has a gift for intricate and living window displays. With the restaurant decked out in holiday cheer, the Christmas spirit is in the air.
