Big Bang Theory Quote
Sheldon: Hello. I am theoretical physicist Dr. Sheldon Cooper, auditioning for the role of Professor Proton. Now, excuse me while I get into character.
(he turns around, then back to face the camera)
Sheldon: Hello. I am Professor Proton. And today, boys and girls, we're going to have fun with science. Did you know you could calculate the mass of an electron using household items? It's true. All you'll need is a pencil, some paper, dry ice, rubbing alcohol, and a spool of 50 micron-thick cobalt-60 wire. And remember, don't put it in your mouth, or instead of becoming a scientist, you'll become wildly radioactive.
Amy: Hang on. I have a question. Do you have any experiments that aren't life-threatening?
Sheldon: Come on! That was a perfect take and you ruined it.
(he does his "enraged" expression)
Sheldon: Oh, look! Hey, I did need "enraged".
