TV Quote of the Day (‘The Big Bang Theory,’ on How and Why Sheldon’s Learning to Swim)

Leonard Hofstadter (played by Johnny Galecki): “What I'm trying to say is that maybe you can't approach this as a purely intellectual exercise.”

Sheldon Cooper (played by Jim Parsons): “What do you mean?”

Leonard: “Well, uh, remember when you tried to learn how to swim using the Internet?”

Sheldon (protesting): “I did learn how to swim.”

Leonard: “On the floor.”

Sheldon: “The skills are transferable. I just have no interest in going in the water.”

Leonard: “Then why learn how to swim?”

Sheldon: “The ice caps are melting, Leonard. In the future, swimming isn't going to be optional.”— The Big Bang Theory, Season 3, Episode 13, “The Friendship Algorithm,” original air date Jan. 19, 2009, teleplay by Chuck Lorre  and Steven Molaro, directed by Mark Cendrowski
