The Flintstones, Season 6 (1965)

Man:
You're a little late for Halloween, aren't ya, buddy?

Fred:
You're not Barney.

Man:
Who?

Fred:
Barney Rubble. Doesn't he live here?

Man:
[laughs] That's a hot one. B.J. Rubble the multimillionaire living here? You're a regular comedian, mister.

Fred:
Barney Rubble a millionaire?

Man:
Yeah, struck it rich in oil years ago. Mr. Rubble lives way up there on tip of that hill. Calls the estate Sandstone Simeon. Everyone knows about B.J. Rubble the millionaire. You must have been asleep for the last twenty years, pal.

Fred:
Gee, maybe he's right. Maybe I have been asleep for twenty years, like in that Rip van Winklestone story. [starts crying] I've slept my whole life away! My family's gone, my friends disappeared, Barney is rich! Barney, he'll remember me! I'm his best friend and he'll know where Wilma and Pebbles are!
