How is religion like a penis?

While examining the body of Mr. Schwartz, a mortician notices that Schwartz has the largest penis he has ever seen.
"I'm sorry, Mr. Schwartz," says the mortician, "But I can't send you to be cremated with a tremendously huge penis like this. It has to be saved for posterity."
The mortician removes the penis, places it in a jar and puts the jar in his briefcase.
When he gets home, he decides to show it to his wife. "I have something to show you that you won't believe," he says, removing the jar from his briefcase.
"Oh my God!" she screams, "Schwartz is dead?"
