Quotes:
From "The Big Bang Theory: The Dumpling Paradox (#1.7)" (2007)
Leonard: Penny, if you promise not to chew the flesh off our bones while we sleep, you can stay.
Penny: Wh-what?
Sheldon: [glaring at Leonard] He's engaging in reductio ad absurdum.
Penny: [speechless]
Sheldon: It's the logical fallacy of extending someone's argument to ridiculous proportions and then criticizing the result. And I do not appreciate it.
