Two brothers Funny Clean Joke

Two brothers, Rob and Bob, found themselves a job on a ship.
Rob had really large eyes and Bob had huge ears.

The captain of the ship asked them, "What can you do?"

"Well, I can be a lookout," said Rob, the fellow with the large eyes.

"What will he do?" asked the captain.

"Well, he's my brother, Can't leave him alone. He'll come with me." replied Rob

The captain agreed and said, "All right you can be lookout and take him with you to the crow's nest and keep him out of my face!"

They had been at sea for a fortnight when the whistle from the crow's nest sounded in the wheelhouse!
"Ship bearing port 10."

The captain looked at the radar, not an echo on the scope. "Are you sure?" he asked.

"Positive," replied Rob, "and what's more, its Chinese."

"How do you know that?" the captain asked.

Rob replied, "My brother Bob can hear them talking!"
