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?"
