Chappelle "freaked out" during the flight Friday and would not buckle his seatbelt, TMZ reported. He then "walked into the cockpit, asking how much longer the flight would be, and started grabbing the pilot's arms," TMZ said, citing a source who was "extremely familiar with the incident."
Chappelle, 36, then checked into a hotel, where sources said he asked to rent a car to drive to his home in Ohio -- but he couldn't remember where he lived.
A spokesman for the comedian told TMZ Chappelle desperately needed to use the restroom and that the facilities on the plane were "not the kind he needed."
