See You Space Cowboy... 

At the end of a Cowboy Bebop episode, there is a black screen, with a subtitle that says "See You Space Cowboy.."

It's the show's way of saying "Goodnight" to the audience..

It is a cool way of saying goodbye to a friend too, or a possible replacement for "peace."

E1:
*End of Cowboy Bebop episode*
See You Space Cowboy...

E2:
Guy 1: See You Space Cowboy.
Guy 2: Later man.
