« PENNY : Sheldon, do you want to sleep here tonight?
SHELDON : Oh as small as Leonard is I don't think you two would
be comfortable on the couch
LEONARD : So... what do you want ?
SHELDON : It's not what I want, it's what evolution wants, human beings are
primates, primates have evolved to live in groups, both for protection
and support !!
LEONARD : But you don't like other people
SHELDON : I do tonight, it's scary over there
LEONARD : It's getting scary here too ! »
