"Sheldon! Stop it! You're hurting me! What the hell are you doing?!"
"You never saw me coming, did you?"
"Let go of me, you son of a bitch!"

"What—Sheldon, no! Please, I know what you're thinking—"
"Mmm—I'm sure Zack appreciates the thong. But for tonight, I'll appreciate it—on the floor, of course."
"Sheldon! God, please, don't do this!"
"Give me a reason not to."
"I'm your sister! I'm your sister, Sheldon!"
"I said a reason not to, Teresa."
Teresa screamed.
