The first time I heard about that place called "Easter Island", an image vaguely similar to this popped into my head. It's as good an explanation as any for why those giant head things might be there. This is, of course, from Non Sequitur by Wiley Miller.
Speaking of Easter, please forgive the following:
Knock knock. Who's there? Ether. Ether who? Ether bunny.
Knock knock. Who's there? Samoa. Samoa who? Samoa ether bunnies.
Knock knock. Who's there? Estelle. Estelle who? Estelle Samoa ether bunnies.
Knock knock. Who's there? Consumption. Consumption who? Consumption be done about all these ether bunnies?
