Okay, so I had this as an assignment in one of my classes, and it sparked a very heated argument. Me, being the psychology major, thought it was really interesting xD;; So, I want to see what you guys think. Some of you may have seen this before.
[SPOILER="Spoiler"]The citizens of Gary, Indiana own a boat that they have named The Great Gary. In 2000, they enter it for the first time into the annual Lake Michigan race. The Great Gary beats all the other boats, and the citizens of Gary are very proud of their civic achievement. For the next seven years, The Great Gary always wins the Lake Michigan race.
In 2008, there is a very bad storm, and The Great Gary suffers heavy damage when it is banged against the pier by the high waves. About half the boat's parts need to be replaced. After the citizens of Gary repair their boat, they do not want to throw away the damaged parts because they consider them of historical value. Instead, they take all damaged pieces to the Gary Boat Museum. The repaired Great Gary is returned to Lake Michigan, and it wins more races.
Meanwhile, some of the Gary schoolchildren come to the Gary museum on a field trip. As a class project, they take the damaged pieces and assemble them in the exact shape of the original Great Gary. Not all the boat was damaged, of course, so there are some gaps, but the museum curators generously buy a few extra parts to fill in those gaps.
The museum curators then have a brilliant idea. They put the reconstructed Great Gary as a museum exhibit and charge museum visitors $5 each to see "The Original Great Gary!"
This works well, and the museum curators are making a lot of money, until the captain of The Great Gary visits the museum one day and sees the exhibit. Furious, he demands to see the chief museum curator. "What do you think you're doing?" he shouts. "That thing in the glass isn't The Great Gary! The Great Gary is currently docked in Lake Michigan after having won the latest Lake Michigan race!"
"Your ship that has just won the latest race may be The Great Gary," says the museum curator, "but this museum exhibit is also The Great Gary."
"They can't both be The Great Gary!" exclaims the captain.
Is the captain right when he says there can't be two Great Garys? And if so, which boat is the real Great Gary?
As time passes, the ship on Lake Michigan suffers additional problems and undergoes additional repairs. A day finally comes when the last piece of the original Great Gary is removed and taken off to the museum. However, a replacement part is always installed so that there is always a functioning ship on Lake Michigan that continues to call itself The Great Gary.
Now that every piece of the original ship has been replaced by a new part, is the ship on Lake Michigan still The Great Gary? And if not, how many pieces did it lose before it ceased to be The Great Gary?[/SPOILER]
