How Many of These Apple Easter Eggs Have You Seen?

"Apple has a history of placing easter eggs -- hidden, and sometimes funny objects, text, or apps -- in their hardware and software over the years."

This is what you saw inside the Macintosh 128 in 1984, signatures of the team done inside the case. I think the funniest is the blue screen of death icon when the network detected a Windows PC connected. Of course, the best is the Sosumi egg, interesting story indeed! What is your favorite?
