Big Bang Theory Quote
Sheldon: Leonard, this is going to haunt me for the rest of my life. Every science classroom, every periodic table, every textbook, this mistake will be staring back at me, like that time you let Koothrappali wax your eyebrows. I've got to find a way to stop this thing.
Leonard: Buddy, I don't think you can. I mean, once it's out there, it's out there. This thing is like the science equivalent of a sex tape.
Sheldon: You know, frankly I'd prefer a sex tape.
Leonard: You don't know what a sex tape is, do you?
Sheldon: No.
