Dad and his shark son are swimming through the ocean when they come across a shipwreck with people in the water.
The son says 'can we eat them?' The dad says 'yes but first of all we have to swim around them with our dorsal fins out of the water'. They swim around them and the son says 'can we eat them now'. 'Lets just swim around them again with our dorsal fin out of the water' says dad, which they do. Dad says 'now they are good to eat'. They feast and after it the son says 'Dad why didnt we just eat them' Dad says 'It was to make them taste better as it scares the crap out of them!!'
