Sheldon: Howard, please, I'm begging you.
Leonard: Raj, you're our group historian. Has Sheldon ever begged before?
Raj: Three times. He begged the Fox network not to cancel Firefly. He begged the TNT network to cancel Babylon 5. And when he got food poisoning at the Rose Bowl Parade, he begged a deity he doesn't believe in to end his life quickly.
