This is the story of Peter and Jesus in the boat as I remember it being told to me as a child in Sunday School. Recently, after all these years, I actually opened a Bible, found the passage and realised either the person who told it to me got it completely "wrong" or my memory is playing tricks on me. Either way, I prefer the "wrong" version:
Jesus and Peter are in a boat. Jesus is passing his spare time by walking on the water by the boat. Peter says to him, "That's so wicked, man, I wish I could walk on water like you."
Jesus says, "You can."
Peter says, "Fuck off. You can do it because you're the Son of God."
Jesus says, "Naw, man, anyone can do it. You just have to believe in yourself."
Peter is a little wary, but since it's the Son of God telling him so, he has no choice but to believe. So he stands up and says, "All right man, since it's you saying so, I will at least give it a try."
He steps out on to the water. Shazam! He's walking on water. In disbelief he looks back at Jesus to say, "I did it, I fucking did it man!" but the instant he pronounces the word "I", bang, he splashes down into the water.
Jesus tells him: "Peter, there's no 'I' doing it. Only God, man. Only God."
