An atheist was quite incensed over the preparation for Easter and Passover holidays and decided to contact the local ACLU about the discrimination inflicted on atheists by the constant celebrations afforded to Christians and Jews with all their holidays while the atheists had no holidays for them to celebrate.
The ACLU jumped on the opportunity to once again pick up the cause of the downtrodden and assigned their sharpest attorney to the case.
The case was brought up before a learned judge who, after listening to the passionate presentation by the ACLU representative, promptly banged his gavel and said, "Case dismissed!"
The ACLU lawyer stood up and objected to the ruling and said, "Your honor, how can you dismiss this case? Surely the Christians have Christmas, Easter, and many other observances. And the Jews--why, in addition to Passover, they have Yom Kippur and Hanukkah ... and yet my client and all other atheists have no such holiday!"
The judge leaned back in his chair and simply said, "Obviously your client is too confused to know about or for that matter even celebrate the atheists' holiday!"
The ACLU lawyer pompously said, "We are aware of no such holiday for atheists--just when might that be?"
The judge said "Well, it comes every year at the same time--April 1st!"
