This episode was produced from December 6 to December 12 of 2018.
It was announced via a press release that the title was going to be "Man Cave Self Destruct," but it was changed.
Ray's private man cave is marked as "Raw Sewage," so when Schwoz, Jasper and Charlotte respond with their own private man cave, their door is marked "Cooked Sewage."
Seen briefly in the Mannex (Ray's man cave annex within the Man Cave), Ray somehow managed to finally get his hands on a framed photo of Henry's mom.
This is the 100th episode of the series.
