An atheist a theist and a militant agnostic are in class in primary school and the teacher is going over their times-tables. They’ve been taught the basic principle and their two, three and four times table when the teacher writes up a more difficult problem on the blackboard:
7 x 8 =?
The theist answers: “Three hundred and seventy two!”
The atheist answers: “I don’t know, but I’m pretty damn sure it’s not three hundred and seventy two. Can I check on my calculator?”
The militant agnostic answers: “I don’t know, and neither do any of you other fuckers!” Then storms off in a huff.
