Conversation so far:
What was surrealist about The Goon Show?
characters would announce their departure but another character left the room. That character would then beat on the door for re-admittance, and the wrong character would be locked out.

Question: Are there other examples of surrealism in the show?
Self-contained rewrite: Are there other examples of surrealism in The Goon Show besides different characters leaving the room and wrong characters being locked out?
