Police Academy 4 carries the banner of tasteless humor raised in the first three installments to new heights of insipidness. As usual, Steve Guttenberg leads the proceedings as Mahoney, the cute cop. Instead of just resembling a puppy dog, he actually imitates one at one point.
Most of the regulars are back with Bobcat Goldthwait assuming a larger role as the moronic cop Zed, who spends most of his time chasing birdlike Officer Sweetchuck (Tim Kazurinsky). Bubba Smith growls his way through a few scenes and Leslie Easterbrook as the statuesque Officer Callahan gets to show off her talents as well.
Plot, such as it is, has something to do with Commandant Lassard’s (George Gaynes) Citizens On Patrol program and attempts by archrival Captain Harris (G.W. Bailey) to make him look bad, a truly difficult task since collectively this police force barely has a triple digit IQ. Script is merely a collection of gags tied together by the slightest suggestion of a story.
