Not originated by the Animaniacs, this was a running gag in vaudeville... a catcall to call attention to a fine looking individual passing by.
*scantily clad curvaceous person sashays into line of sight*
"Hello Nurse!"
or more appropriately
"Helllloooooo, Nurse!"
"Hello Nurse!"
or more appropriately
"Helllloooooo, Nurse!"

Derived from Animaniacs, a person who is so visually appealing to all that you must draw attention to them by saying "hellloooo nurse".
**walking down the street when the hottest looking guy ever walks past you, you whistle appreciatively, turn to your friend and say "hello nurse".
