Not exactly the sight you want to see when riding in a small boat.
For a father and son on a fishing trip near Massachusetts, a very large visitor decided to stop by and say hello.
In a YouTube video uploaded by Jack Gibbons, you can see a large great white shark circling their boat just offshore.
"He's coming, and he thinks we're dinner," said the man jokingly in the video.
After a few minutes, the shark disappears in the waters below.
