First of all, you links to the original article are broken. Second, this is pretty silly.
Two conspiracy theorists die and go to heaven. They spend their first days of eternity listening to lilting music, enjoying peace and tranquility. Then one day they are walking through the gardens and they see Jesus Himself walking towards them. He asks them how they are liking Heaven.
“Well,” says one. “It’s just fantastic!”
“Good,” says Jesus. “I’m very glad you’re enjoying it.”
“Um,” says the other. “Look, I know this is a bit cheeky, but surely you will know the answer. Can you tell us who really did kill Kennedy?”
Jesus looks at them and says “Yes I can tell you, but I don’t think you are going to like the answer”.
“That’s alright,” says one of them. “We have to know.”
“Very well,” says Jesus. “The truth is that Lee harvey Oswald, of his own volition, shot and killed Kennedy, and then Jack Ruby, of his own volition, shot and killed him.”
There was a pause, and then one theorist turns to the other and says “The conspiracy goes deeper than we thought.”
