Ham and Cheese: David Warner is capable of some quite brilliant, subtle performances. For this movie, however, he puts in about as much effort as Jeremy Irons did in Eragon, or, frankly, Sir Alec Guinness did in Star Wars.
Narm: That one dwarf bandit, swinging around on a rope, shrieking "I'm comiiiiiiiing!" It would be funny on its own, but he keep screaming it over and over.
Also, Tee's Smurf hat.
Nausea Fuel: Baydool weaponizing his chamber pot to scare off a man sneaking around his property.
The Scrappy: Leonardo da Vinci. He was supposed to be a Lovable Rogue, but to most people just comes across as whiny and unprincipled.
