Big Bang Theory Quote
Amy: You have sporting equipment?
Sheldon: Well, oh, un, It's just, it's a golf ball that my brother threw at my head. You can still feel the dent. It's right next to the hockey puck dent.
Amy: OK, why do you have a bin of pinecones?
Sheldon: I used to collect them as a child. The spiral of scales open in the Fibonacci sequence. A fact that when you tell your brother gets a golf ball thrown at your head.
