Wamthool: I think I got it! Mike: Yes, I got the role in Mad About You!
The Alleged Robot: While Gypsy repairs the original Crow, she gives Mike and Tom a "loaner Crow" that she's been tinkering with. He can't speak coherently, he shakes constantly and smoke keeps belching out of him - but he's got a killer stereo!
Bizarro Episode: Pearl, upset with Mike's mental health and upbeat nature despite repeated viewings of bad movies, swaps places with him for the first quarter of the show. Pearl dons a jumpsuit and riffs alongside the 'bots in the theater, while Mike hangs out with Bobo and Brain Guy back at the castle.
Continuity Nod: In the opening host segment, Crow goes in for repairs and is temporarily substituted with a less than optimal Fake Crow. When the real Crow returns, he says that Gypsy needs Fake Crow immediately; some other guy's Crow got trashed and he needs a loaner. The Continuity Nod part is the fact that there is another Crow - the one who stayed in the past over the course of Time Chasers.
Loaner Crow is actually the older version of the Crow puppet from the Comedy Channel era, recognizable by his slightly longer "beak" and duller-colored eyes.
Special Guest: Leonardo da Vinci shows up in an ornithocopter-spaceship and complains (in a thick Brooklyn accent) about the movie's portrayal of him, calling the twerp in the film a "mook." When Servo wonders how Leo's still alive, the feisty Italian takes it as a threat and goes for his gun. At the end, Mike concludes that it's not a good idea to ask what Leonardo da Vinci does for a living.
