Another one of his movies has him holding onto a helicopter's rotor blades as it lands. He sneaks into the castle and kills the Russian businessman and attacks the other villains there.

Homer's hallucination
Homer started to hallucinate after getting a concussion. Stradivarius Cain taught Homer how to be a better lover to Marge by telling him to flirt with other women to teach him how to be kind to his wife. After angry husband threatened to shoot Homer after he flirted with his woman, Cain told Homer to squirt a lemon in his eye, then a lime. They both ran off and Cain seemed to enjoy it.

Cain tells Homer to clean out his car after wondering where the hidden weapons are. Homer said that his nagging was making him like a second wife so Cain transforms into a woman to tell Homer that he can do that. Later, when the same angry husband tried to kill Homer again, Homer bashed his head to get his hallucination back. Cleatus the Football Robot unzips itself and out steps Cain who tells Homer to flirt with the man, the same way he did so with his wife. Homer does so and Cain's work is done when Marge realizes that Homer wanted to please her.
