Sheldon: Leonard, have you ever wondered why my little toes and lateral incisors are significantly smaller than the average for someone of my size? Leonard: I wonder a lot of things about you Sheldon, but not that
Sheldon: How am I going to get to work? Leonard: Take the bus. Sheldon: Oh, I can't take the bus anymore. They don't have seatbelts, and they won't let you lash yourself to the seat with bungee cords. Leonard: You tried to lash yourself to the seat with bungee cords? Sheldon: I didn't try; I succeeded.
