Police Academy - Season 1 Episode 3 Phantom of the Precinct

More and more officers are being scared into taking extended leave, following ghostly encounters with the crooked Phantom. Captain Harris thinks this would be a great way to rid the force of a few certain individuals, and puts Mahoney and friends on the case. But when Sweetchuck is kidnapped by the Phantom, the team follows the trail to Hearse Castle, where they have to deal with a barrage of the Phantom's magic tricks to try and save their comrade. However, the secret to catching this ghastly ghoul might just rest with Sweetchuck himself.
