Sharks

Daddy shark and teenage son shark come to the site of a boat capsize and notice 4 people in the water. Daddy says to his son, now I'll show you what you do with them.

First we swim around them with just the tips of our fin out the water. They complete two circles and then daddy says OK now we do it again with all of our fin sticking up out of the water. They complete two circles.

OK says daddy shark, now we eat all four.

After eating the son asks, what was all the swimming in circles and showing fins thing about ?

Daddy says, they taste better after you scare the sh-t out of them.
