Jesus, St Peter and Uncle Sir Bobby Robson were in a fishing boat. Jesus gets out of the boat and walks across the surface of the water to the shore. Peter is amazed, and Jesus beckons for them to follow him. Sir Bobby stands up, gets out of the boat and he too walks across the water to the shore. Peter is flabergasted, but plucks up the courage to do the same. He steps out of the boat... and sinks like a stone.

A few minutes later, Peter scrambles onto the shore - Jesus says to him "Why didn't you use the stepping stones?". Sir Bobby looks at them both and says "What stepping stones????!!!!"
