Dr. Screwball Jones is a character from Disney's Wander Over Yonder, first appearing in Season 2.
He is voiced by Weird Al Yankovic.
Dr. Screwball resembles a floating banana with a clown wig, bow tie, top hat, glasses and a doctor's head mirror. He also has a large moustache which also take the place of arms.
Wander mentions Dr. Screwball as being a villain of his past. Like Wander, his goal is to spread joy across the universe, but does so by forcing people to laugh, which Wander is against since he believes happiness is meant to be found freely. Screwball is known to constantly tell jokes and his schemes involve practical joke materials.
The Boy Wander
Telling by a missing feather and a whoopie cushion, Wander realizes his old foe has returned. Going undercover, he goes on a quest to take down Screwball. The villain, meanwhile, steals feathers from a museum and an alien race. He later introduces himself, revealing to have created a tickle machine, which he inflicts on an entire planet, as well as Lord Hater and Commander Peepers. When Sylvia falls victim to Screwball, he and Wander engage in a musical duel. Just as all hope seems lost, Sylvia manages to break Screwball's machine, causing it to backfire on him as his blimp is sent away.
