Big Bang Theory Quote
Penny: I got some candles in my apartment.
Sheldon: Candles, during a blackout! Are you mad! That's a fire hazard. No, Pasadena Water & Power recommends the far safer glow stick.
Leonard: You call that a glow stick?
(Pulls out a glowing lightsaber replica)
Leonard: That is a glow stick.
