'Pants on the Ground' Joins the Mile High Club

Gen. Larry Platt just took in-flight entertainment to the next level.

Platt's manager tells TMZ Platt busted out an impromptu performance of "Pants on the Ground" during a flight from L.A. to Atlanta this AM -- after passengers recognized him and then begged him to do it.

We're told Platt -- who was on his way back home from The Grammys -- performed the song in the aisle in coach.

Platt was the last person to get off the plane -- because the pilots and flight attendants wanted to meet him.
