Piratish way to share

A young man saw an elderly pirate couple at a restaurant. He noticed that they had ordered one meal and an extra cup. Being somewhat stereotypical pirates, one had a peg leg and the other had an eye patch.

As he watched, Pirate A carefully divided the fish filet in half, then counted out the fries until each had half of them.

Then Pirate A poured half of the beer into the extra cup and set that in front of Pirate B. Pirate A then began to eat, while Pirate B sat and watched. 

The young man decided to ask if they would allow him to purchase a second meal so that they would not have to split theirs. But Pirate A said, "Oh no. We've been married for 50 years, and everything has always been, and will always be, shared fifty-fifty.

The young man then asked if Pirate B was going to eat. The response? 
"Not yet. It's A's turn with the teeth."
