Clark Gable's Grandson -- 10 Days in Jail for Lasering Police Chopper

Clark Gable's grandson Clark Gable III was just sentenced to 10 days in jail for flashing a laser pointer at an LAPD chopper.

23-year-old Clark pled guilty last month to one felony count of discharge of a laser at an occupied aircraft -- after pointing the thing at an LAPD helicopter, flying over some event in Hollywood last summer.

Cops in the aircraft were somehow able to pinpoint the laser coming from the small red car Gable was riding in. The car was quickly pulled over and Gable was arrested.
