The reason that Jesus was able to rise from the dead is that he was fed on a diet of rabbit eggs. This closely guarded secret, that bunnies lay magic eggs, was passed down to Joseph and Mary by the three wise men. "The gift of the magi" was a batch of three magic bunnies, a male, a female and a shmale (magic bunnies have three sexes). The reason Jesus was born in a stable was that they had to be able to hide the bunnies and keep them warm while they produced magic bunny eggs.
Alas, there are no known magic bunnies in existence now, although some may be kept secretly. (There are those who assert that the reason Dick Cheney is still alive after all those heart transplants has something to do with magic bunny eggs.)
Nowadays, there are no magic bunny eggs available, so Christians make do with chicken eggs.
And that, Virginia, is why we fool around with chicken eggs on Easter.
