 When Tom Ruegger (qv) created Buster Bunny for  _"Tiny Toon Adventures" (1990)_ (qv) he wanted to create a catch  phrase (to parallel Bugs "Whats up, Doc?"). All he could think of  was the old vaudeville standby "Hello, nurse!" but that made no  sense for the character. Now the phrase is used by Yakko and Wakko  when greeting Dr. Scratchansniffs attractive assistant.
