A gun falls out of a sleeping man's pocket...Stop us if you've heard this one.

Houston police are investigating the apparent accidental shooting of 20-year-old Patrick Sanders Saturday after a gun fell out of his pocket during a nap and landed in the hands of an infant.

Sanders was napping on the couch in the living room of his apartment on the 4700 block of Wenda Street Saturday morning, according to an HPD report, when the gun stashed in his pocket slipped out and onto the floor.

The man awoke to find it in the hands of the three-month-old boy, HPD Homicide Division Sergeant R. Rodriguez and W. Gilbert reported.

Sanders apparently tried to grab the gun from the infant, which caused the gun to fire. Sanders was shot in the face.

The gun-toting child was not injured during the incident, according to the police report.

Sanders was transported to Ben Taub General Hospital, where he remains in critical condition.
