Somebody should edit the article about the episode of Pee-Wee's Playhouse called "Ice Cream Soup." The secret word is door, but only Pee-Wee screams when the salesman says, "I'm going door to door to make you this incredible offer..." and Pee-Wee does that because the salesman appears, not because the salesman says the secret word.

This is why I love RetroJunk.
