TV Quote of the Day (‘The Big Bang Theory,’ With Proper Perspective on Fear of Heights)

(Sheldon, in an attempt to gain access to a computer, decides to try to make friends with Barry Kripke, even if it means bonding through an unfamiliar activity like rock climbing.)

Barry Kripke (played by John Ross Bowie): “You afwaid of heights, Cooper?”

Sheldon Cooper (played by Jim Parsons): “Hardly. A fear of heights is illogical. Fear of falling, on the other hand, is prudent and evolutionary.” — 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
