Nurse
The buxom blonde studio nurse (though she has a habit of appearing in various other occupations as well), voiced by Tress MacNeille, over whom Yakko and Wakko continually fawn. Her appearance almost always prompts the boys into lustfully exclaiming "Hellooooooo, Nurse!" and jumping into her arms. They will also call out her name if they see a beautiful female creature as shown in the episode Meet Minerva. Dot does likewise when an attractive man enters the picture. She also appears in a few Slappy cartoons, as part running gag where her response to one of Slappy's jokes or sarcastic comments is "Huh, I don't get it?" (sometimes this followed by the sudden appearance of the Warner Bros. who chase her off), which is consistent which her portrayal stereotypical dumb blonde. In at least two of Slappy cartoons, she is shown working for an airline once as a stewardess in "Bumbie's Mom" and airline ticket seller in "Gimme A Break". In Wakko's Wish, it's revealed that her "mean IQ [is] 192" (compare to Albert Einstein's IQ of 160). In the latter characterizations, she laments that she is respected only for her looks and not her mind.
