The Pope took a philosophy professor (an atheist at that) out fishing on
  a large lake. As they drifted on the still lake, the philosopher
  accidentally dropped an oar and watched it float away. The pontiff
  stepped out of the boat, walked across the water to the oar, grabbed it
  and walked back to the boat. The next day at the university, a colleague
  asked the philosopher if he had enjoyed fishing with the Pope. "It was
  okay, but would you believe that guy can't swim?"
