The World's Oldest Woman is one of the hosts from the Warner Bros. Animation television series Histeria! First appearing as a nameless recurring extra on Animaniacs, she is an elderly woman who, as her name suggests, is as old as time itself (she could possibly be related to Father Time, though it is never mentioned). Having lived for such a long time, she has supposedly dated many famous men throughout history, and even been married to several such men.

The World's Oldest Woman with the CEO of Rockyfellow Center in "The Christmas Tree".
One of World's Oldest Woman's cameos on Animaniacs came in the original show's final Christmas segment, "The Christmas Tree". When Slappy Squirrel moves the Rockyfellow Center CEO's house into the middle of Times Square (in retribution for her tree being placed in Rockyfellow Center to begin with), the World's Oldest Woman appears, doing her grocery shopping in the middle of his house.
Histeria![]

The World's Oldest Woman with George Washington.
In Histeria!'s only Christmas-themed sketch, titled "The Banks of the Delaware River" (which appears in the episode "The American Revolution - Part 1"), World's Oldest Woman appears as the storekeeper for a boat rental service near the Delaware River. On Christmas Eve in 1776, George Washington comes to rent her boats so he and his troops can cross the river and strike their surprise attack on the Hessians hiding out in Trenton, New Jersey. World's Oldest Woman tells the future first President of the United States that renting her boats will not be cheap, as he will need to pay a big stack of hundred-dollar bills. Washington, sensing patriotism in the elderly lady, tries to pay with a check, but World's Oldest Woman will not agree to that. After a quick scene transition, World's Oldest Woman, having been paid with a wheelbarrow full of money, is last seen seeing off Washington and his troops as they begin crossing the river with her boats.
