My Mother The Alien - S2-E9

Other mistake: When Harry spits baby food on the baby (the camera lens in actuality) in retaliation for the baby spitting food on him and Tommy, Joseph Gordon-Levitt breaks character and laughs uncontrollably and looks at and gestures to off-screen crew members a couple times. (00:06:25)

Sally: You know, I just really resent how we're supposed to jump every time the Big Giant Head sends a message.
Dick: I know. Everyone knows he only got the job by kissing the big giant butt.

Dick's Big Giant Headache (1) - S4-E23

Trivia: When the Solomons meet the Big Giant Head at the airport and ask how his flight was, he says that it was horrible because when he looked out the airplane window, he saw something on the wing of the plane. Dick responds that the same thing happened to him. William Shatner appeared in the 1960's Twilight Zone episode "Nightmare at 20,000 Feet" in which a gremlin tried to destroy the wing of a plane. John Lithgow appeared in "Twilight Zone: The Movie" playing the same character in the same situation.

Question: In many episodes, Dick and Mary will go together to a destination, but not leave together. Did one of them walk?
