Cheery Theerlap, Lloyd is the tenth episode of Season 3 of Lloyd in Space, which was first broadcast on October 31, 2002.

Lloyd tries to get out of singing holiday songs for Droimatz (their version of Christmas) to read his comic book by claiming he celebrates Theerlap, even though he knows nothing about it. When he finds out there's not much to it, he makes it bigger than it is, and ends up offending his grandpa, the only one who truly knows about Theerlap, by doing so.
