A famous treasure hunter went out one day with all of his diving gear to search for a treasure box that was supposed to be on a sunken ship. He swam around for a while and looked where it was supposed to be, but didn't find anything.

When he was walking out of the water, really close to the shore, he tripped on something. He started to dig around it and it was the treasure chest he was looking for.

All this goes to prove that booty is only shin deep!
