(Sheldon suggests taking up jogging)
Penny: Have you ever run before?
Sheldon: Certainly! I've run from bullies, dogs, angry chickens and one particularly persistant P.E. teacher determined to bend me over and give me a scoliosis test.
(Raj whispers in Howard's ear)
Howard: You're right, Penny jogs. Maybe you guys can run together.
Sheldon: That's an excellent idea! If we chat it will create the illusion of time going faster!
Penny: No, it won't.
