Alien code: In the opening sequence of convoy trucks going by, one of the trucks has Alien Code #1 written on it. When translated it says: "Human Milk."
Alien code: When Fry walks into the truck-stop bathroom, there is a ton of Alien Code #1 written on the wall. While most of it is just single letters, there is one phrase you can read on the calendar. It says: "For A Good Time Call..."
Alien code: Alien Code #1 makes another appearance when Fry and Leela are walking down the block and run into Sal from the truck-stop. It says: "Watch For Falling Humans."
Alien code: In the season 3 DVD, there is a section where you can learn how to draw Fry. The background is from the truck-stop bathroom. On the wall we see Alien Code #1. When translated it says "For a moderately good time call 555-1972!"
When Leela and Fry are sitting at the cafe table, she says, "Fry, let me axe you something." The idea of her using axe instead of ask comes from the episode "Xmas Story" where Leela says that the word Christmas mus be an old form of the word Xmas just like some people say axe instead of ask.
