Stop! Or My Mom Will Shoot (1992)

Stop! Or My Mom Will Shoot is the comical story of Joe Bomoski, a cop on the Los Angeles police force, and how his everyday life becomes chaotic when his mother comes to visit. Joe's mother, Tutti, is a very sweet little old lady that still thinks of her son as her "Little Joey". Tutti proceeds to interfere in every aspect of Joe's life, including his relationship with his girlfriend, Gwen, who also happens to be Joe's Lieutenant. One day while Tutti is cleaning up Joe's apartment, she decides to clean Joe's gun as well...with Ajax. Joe becomes very upset when he discovers that his revolver is now ruined because of the cleaning. Feeling remorseful about the incident, Tutti sets out on a shopping spree to buy her son a new pistol. She meets up with a sleazy character who convinces her, as she loves a bargain, to purchase the weapon from him and his friend. As she leaves the alley with her purchase, she turns just in time to see a car speed down the alley and kill the men she has just bought the gun from. She goes to the police station to report the murder, but won't give any information to anyone but "her little boy". Now Joe...and his mom, take us through their ridiculous escapades as they try to capture the murderers.
