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 on a Roll - S3-E12

Trivia: Dick is never seen walking in this episode and is only in an upright position when he moves from the chair in the lounge room to the wheelchair in the opening scene. This is because John Lithgow hurt his ankle playing tennis, and the episode was written to allow him to be in a wheelchair for the entire episode.

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