ALIEN, THE Easter Egg - Beatles Magical Mystery Tour Reference

On page 15, where Jack and Kenny are in the car on the way to the diner, Jack says that he had his recurring dream again.
Kenny asked, "The one where you're the waiter shoveling the spaghetti onto the fat woman's plate?"

This is a reference to the "Jessie's Dream" sequence in the Beatles' movie "Magical Mystery Tour" where John Lennon plays a waiter shoveling spaghetti onto Jessie's (the fat woman) plate.
John Lennon later claimed that he got the idea for that part of the movie because it was a dream he had just had.
