If you read the bible (the free book in hotel rooms in case you run out of toilet paper) you will know that jesus lived by the sea.
Living by the sea is very useful if you want to be a fisher of men, or a fisherman or - more importantly, catch some waves.
Dog, (being an anagram) said to his prototype:-
"I have invented the tree, and it's full of wood and stuff"
His son was busy smoking and talking weird, and growing a beard but remembered his training as 'Son of a Carpenter'
Thus, from the mighty tree, jesus did plane and polish to create - The Surfboard.
Although, a mighty fine idea, young master jesus has no idea HOW to surf.
"I have this really good idea" said JC "might work, might not"
As JC walked across the water, the disciples sat on the beach, stroking their beards.
When his dad created a huge wave of love, JC rode on it and proclaimed
"Yay - hanging ten"
at which point, most of the disciples, being wise, ran away.
When he arrived on the beach, he said to those remaining "I will teach you, and the you can teach others".
And thus they practiced - a lot.
Killed a lot of fish in the process too.
