The Big Bang Theory nurse!

Beside the main characters of the show and those who have been introduced during the seasons, there is an actress who has been there from the very beginning and has never left the scene: the nurse!

From episode 1, every single time a nurse appears, she is interpreted by the same actress: Vernee Watson.

From the Sperm Bank, to the hospital where Howard is brought because of the arm robot stuck on his private parts, to the room where Sheldon's sick barber is held, Althea (as revealed in her name tag) is always the portrait of The Big Bang Theory nurse!
