It was back in the sixties or seventies. The story was of a boy with what appears to be a bad head/facial disfigurement. He's picked on and called a freak by all the kids in the neighborhood.
He wants to live alone or kill himself when he's offered a chance to move to another planet where his deformity wouldn't be noticed as much. It's an exchange program because the other planet sends their deformed people to us.
The kid from the other planet looks human and considers himself a freak when he looks at his own people. Our boy is surprised when two flight attendants (who have the same look as him) greet him and tell him he's cute.
I try to watch when they do marathons but never seem to find this episode.
