The Atheist and the Zoroastrian

"Our religious beliefs are nearly identical," said the atheist.

"My friend, how can that be?" asked the Zoroastrian.

"Behold, here is a list of 100 Gods: Thor, Zeus, Vishnu, The Great White Spirit, and so on," said the atheist. "Which, if any, do you believe do not exist?"

"Why, 99 of those are complete fictions. Only the great Mazda is real!" proclaimed the Zoroastrian.

"Then we agree 99/100ths of the time," concluded the atheist. "I merely take your principle one god farther."
