Dick Jokes - S2-E11
Dick: You know, it's a remarkable feeling to be able to make someone else laugh. It's almost as if you have the power to get inside their brain and, and tickle it.
Harry: Pssh. I could do that with a chopstick.
Dick: Imagine how different war would be if instead of trying to kill each other, people just showed up armed with jokes.
Sally: But you could still have guns, right? Because, you know, eventually you'd stop laughing and want to get on with the killing.
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)
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.
