Not every Christmas special needs to be heartwarming and festive. It can be just fun, too. Hence Inspector Gadget Saves Christmas, a 1992 special that aired on NBC. There’s not much to say here. Inspector Gadget is called in when Dr. Claw tries to ruin Christmas and I guess Captain Yuletide was elsewhere. Enjoy.
Fun fact: While Don Adams does provide Gadget’s voice, according to Wikipedia Maurice LaMarche (who does an amazing impersonation) provides the singing voice. I don’t know why they didn’t use the usual theme song though.
