I just found this real gem on the Wiki:
Believer: You are so stubborn. I bet if God zapped your butt with lightening, you still wouldn’t believe.
Atheist: Try me!
Suddenly the sky opens up and a huge bolt of lightning flies straight down at the atheist’s rear end and the shock knocks him 10 feet away.
Atheist: I bet you are not God up there; you are just an alien with advanced technology.
Sky: Oh yeah, take this!
Atheist: So you can give me duck feet. You are still just an alien with advanced technology.
Sky: How about this!
Atheist: So, you gave me women’s breasts. You are still just an alien with advanced technology. Nice work, though.
Sky: You have offended the Great Lord one last time. I am ending this now!
(Loud thunder followed by a blinding flash)
Atheist: Wow! That really was God! I have to go tell everybody.
(Atheist runs off down the hill shouting religious slogans)
Believer: God, that was a pretty impressive display. But if you don’t mind my asking, how did you make him believe?
Sky: I simply directly turned his mind into a believer’s mind. By the way, I really am just an alien with advanced technology. Ta ta…
Priest: You know, Scribes, I don’t think you need include that final exchange in the next edition of the Holy Scriptures.
Made my day…
