Hmm, I don't actually know any greek jokes. So lets try and offend some people! Religious jokes:
Martin Luther King, The Pope and Bill Gates die and go to heaven (I don't know, someone bombed a conference/dinner?). They stand before God, in his Throne, and he says to the Pope: "In what do you believe?"
The Pope replies, "I believe in the goodness of mankind and in your benevolence, my lord."
So God says "Very good, take your place at my Right hand side. And Mr. King, In what do you believe?"
And he recieves the reply, "I believe that all men were created equal, and should be treated as such."
"Very Good, please sit to my left. Finally, Mr. Gates, what do you believe?"
To which Bill says: "I believe, you are in my chair."
