Quote from Dick in Brains and Eggs
Dick: Everyone fully formed? Sally: Uh-huh. Harry: Yeah. Dick: Everyone got 10 fingers and 11 toes? Sally, Harry & Tommy: Check. Dick: Good. I guess we're in. Everyone comfortable? Harry: Um, I have three holes in my face. Dick: Can anyone get your head to swivel to the rear? All: No. Dick: Then how are you supposed to lick your back? Tommy: Maybe you do what they're doing? Dick: Look. Life-forms, and they're cleaning each other.
