Third Rock from the Sun has the greatest meta moment in all of television.

John Lithgow and his family, actually alien scouts sent to Earth to prepare for an invasion, await the arrival of their leader, who for some reason is coming in through an airport. A drunk approaches them and they shoo him away, not recognizing him as the leader because they have human bodies as disguises, but when they realize it is him they salute and ask him how his trip was.

The leader, William Shatner, says the trip was awful and they sent him to the wrong airport in NJ, then on the trip to Ohio he saw a man on the wing of the plane, and John Lithgow yells "SAME THING HAPPENED TO MEEEE!!!"

Shatner starred in the original 1960 Twilight Zone episode about a man seeing a gremlin tearing his plane's engine apart, and that episode was remade with John Lithgow in that role for the Twilight Zone movie in the 80s.

I loved this when it aired, I still love it.
