Big Bang Theory Quote
(Sheldon's hot twin sister, Missy, is in town for a wedding)
Leonard: If the wedding's not until tomorrow, why don't you stay with us tonight?
Missy: Oh, I don't think so. Shelly doesn't like company. Even as a little boy, he'd send his imaginary friends home at the end of the day.
Sheldon: They were not "friends". They were imaginary colleagues.
