The Work Song Nanocluster - S2-E18
Trivia: Penny is the only character whose original surname was never officially revealed (she took Leonard's surname when she married him). That said, a close zoom in on a package she receives in season 2, episode 18, "The Work Song Nanocluster" appears to show her surname as "Teller". The creators have said that was simply a default placeholder prop and was never meant to be legible on screen, so it's not canonically her surname.
