The World's Oldest Woman is one of the hosts of Histeria! She first appeared, without a name, on Animaniacs in the Chicken Boo segment "Davey Omelette", and later reappeared in the Slappy Squirrel segment "The Christmas Tree". As her name suggests, she is a very elderly woman who claims to remember when air was invented. She also claims to have dated every historical male in history.
