Sheldon: Is there any reason you're keeping this dead goldfish?
Penny: Damn, I forgot to feed him and that I had him.

Sheldon, I swear to God I'm going to kill you.

Howard

Howard: It's ridiculous that we still have to walk up all these stairs.

Bernadette

Leonard: Mmm, you know, we could throw a dinner party too. Maybe even ask everyone to get dressed up.
Penny: Sure. Just when you say "dressed up" you mean nice clothes, right? Not, like, capes and tights and crap
Leonard: Although...
Penny: No.

Sheldon: I found three bowling pins. Do you juggle these or are you missing seven?
Howard: Juggle.
Sheldon: You health nuts kill me.

His quirks just make you love him more. ... Someone please agree with me.
