*Uh oh, Dave Chappdelle is acting weird again. TMZ is reporting that a private jet had to make an emergency landing in Pittsburgh last night because the comedian was freaking out the pilot.

A reliable source says the flight was headed from New Jersey to Ohio where the comedian lives. During the flight Chappelle reportedly “freaked out” and refused to put his seat belt on. Then — according to sources — Dave repeatedly walked into the cockpit, asking how much longer the flight would be, and started grabbing the pilot’s arms.

At that point it was determined that he was a safety risk and diverted the plane to Pittsburgh.

TMZ says after landing the funny man checked into a hotel, but sources at the hotel said Chappelle told hotel employees he wanted to rent a car to drive back to Ohio … only he couldn’t remember where he lived.

If these accounts are accurate, what a sad situation.
