Big Bang Theory Quote
Penny: (sighs) OK, you know what? I'm gonna come at this in a whole new way. Sheldon, if you try to make a baby with Amy in a petri dish, I'm going to tell your mother on you.
Sheldon: Well, that's no threat. My mother's always wanted a grandchild.
Penny: Really, your deeply religious, born again Christian mother wants a test tube grandbaby born out of wedlock?
Sheldon: (stunned) Curses.
