Pirate Movies were low-budget movies created by the Convenience Store Clerk and his friends shown in the episode iStakeout. Three of these movies exist: Aaarrrg!, Pirates of the Lima Bee-An, and Shiver Me Booty. In everyone's opinion, the movies were terrible.
There is a clip of one of the pirate movies. One pirate and his other assistant tell a victim, "Walk the plank!" and "Sing me a ditty!" to a pirate who responds "Nooo!!". Then, when one of the pirate says, "Dance!", the victim dances.
The pirate movies are made legally, and the police cop said, "There's nothing illegal about bad acting."
