Penny is meeting her ex-boyfriend again, and Leonard has ink on his forehead. Sheldon is gratulating Leonard for this “badge of honor”.
Penny: I just think he’s really changed. We’re having dinner tomorrow night, and I get to wear my new beret. Bye, guys.
Sheldon: Well done, Leonard. The true hero doesn’t seek adulation; he fights for right and justice simply because it’s his nature.
Leonard: Penny’s hooking up with her jerk of an ex-boyfriend and I have indelible ink on my forehead!
Sheldon: That’s your badge of honor, your warrior’s wound, if you will. I was wrong; minstrels will write songs about you.
Sheldon (sings): There once was a brave lad named Leonard, with a fi-fi-fiddle-de-dee. He faced a fearsome giant, while Raj just wanted to pee.
