Lisa Simpson's bald eagle inspiration,
Lisa enters an essay writing contest with a theme of patriotism. She cycles into Springfield forest and declares "OK America, inspire me!", and an eagle lands on a tree branch in front of her and spreads its wings, prompting her to write a brilliant essay that wins the first round of the competition.
from the "The Simpsons" TV series episode, "Mr. Lisa Goes to Washington" (Bald Eagle)
