Airheads

Heavy metal trio the Lone Rangers haven't had much luck getting their songs heard. During their last desperate trip to a radio station, they bring along some genuine looking squirt guns and spontaneously pull them out when they're turned down again. One of the workers at the station escapes being taken hostage and calls the police, and a long standoff ensues until the Lone Rangers can play their demo tape, which the lead singer gave to his now ex-girlfriend.
