When Bob inherits a storage unit, the family meets Chet (guest voice Zach Galifianakis), a former window-dresser who’s been squatting in said storage unit. Invited to crash with the Belchers for the holidays, he designs holiday displays that attract tons of attention… until he starts to come unglued, thanks to his obsession with one particular mannequin. One very off-color display (and one sex-shop visit later), the kids agree to give up their Christmas presents so that Chet can find happiness—bringing full-circle Linda’s reminder, from the top of the episode, that the holiday is about more than just hauling gifts for yourself. (Season three, episode nine, “Bob Rest Ye Merry Gentle-Mannequins”)
