Sharks, sharks, don't live in parks
They live in the deep blue sea
They don't use dishes
But they like to eat fishes
And people like you and me.

John, they don't only bite when you're wet.

You can be on a boat, or a raft afloat,
Stick your arm too close to a tank;
They'll think "What the heck!" when you're out on deck
And not even wait 'til you sank.

Sorry. (not so much)
