Jesus is playing a round of golf with Moses in Heaven and they come upon a water trap.
Jesus turns to Moses and asks, "Didn't you do something with water once?" and Moses says yeah, and proceeds to do the trick where he parts the waters.
Jesus is impressed, and Moses in turn asks, "Didn't you also do something with water?"
Jesus says, "Yeah watch this" and proceeds to step out onto the water, but he sinks almost immediately to his knees. He gets out, gets a running start, and tries again, this time sinking to his waist. He comes out confused and embarrassed and Moses asks, "What was it you were trying to do?"
"I used to be able to walk on water," Jesus replies.
"The last time you tried it," Moses asks, "Did you have those holes in your feet?"
