Apocryphal conversation between an unwary homeowner sitting on his front stoop and a Bible*-toting visitor:
Homeowner: Is that a Bible you're carrying?
Visitor: Yes, it is.
Homeowner: And do you believe it?
Visitor: Yes, I do.
Homeowner: And have you verified it to your own satisfaction?
Visitor: Yes, I have.
Homeowner: Then why in the world do you waste your time believing it?
*Bible or any other revered text.
