Howard Wolowitz: Raj, did you ever tell your sister about the time Sheldon got punched by Bill Gates?
Priya: Oh, God! You're kidding?
Raj Koothrappali: Nope. Gates gave a speech at the university. Sheldon went up to him afterward and said, "Maybe if you weren't so distracted by sick children in Africa, you could've put a little more thought into Windows Vista."
Sheldon Cooper: You're my 15th favorite technological visionary.
Steve Wozniak: Only 15th?
Sheldon Cooper: It's still 6 spots above Steve Jobs. I care neither for turtlenecks nor showmanship.
Steve Wozniak: Yeah, I never got that turtleneck thing.
