Leonard (going to living room): Don’t let this be Sheldon playing bongos. Please don’t let this be Sheldon playing bongos.
Sheldon: Hello, Leonard, do you like my bongos? Bet you didn’t know that I had bongos.
Leonard: Sheldon, it’s three o’clock in the morning.
Sheldon: Three in the morning is a good time for bongos.
Leonard: I was sleeping.
Sheldon: Leonard sleeps while I play bongos.
Leonard: No, he doesn’t.
Sheldon: Leonard no sleep while I play bongos. Bongo solo.
Leonard: Stop! Stop it! Stop! Stop! Stop it!
Penny (entering): What the hell?!
Leonard: Oh, hi, Penny, guess what? Sheldon got bongos.
Penny: Why did you get bongos?
Sheldon: Richard Feynman played the bongos. I thought I’d give that a try.
Leonard: Richard Feynman was a famous physicist.
Penny: Oh, Leonard, it’s three o’clock in the morning. I don’t care if Richard Feynman was a purple leprechaun who lived in my butt.
Sheldon: Penny meant if he were a purple leprechaun. Penny forgot to use the subjunctive.
Leonard: Sheldon, go to bed. You have work in the morning.
Sheldon: Maybe, maybe not. Maybe tomorrow I start a bongo band and tour the world.
Leonard: W-w-wuh, no, no, hang on,uh, uh, roommate agreement. No hootenannies, sing-a-longs, or barbershop quartets after ten p.m.
Sheldon: Roommate agreement? Are you kidding? We are living in a world of chaos. Roommate agreement.
Penny: Where are you going?
Sheldon: Wherever the music takes me, kitten. I play bongos walking down the stairs. (Sound of falling) Oh! Oh! Never play bongos walking down the stairs.
