Morris and his wife Sherry were planning a vacation. They ended up in an argument.  

"It's pronounced 'Hawaii', I'm telling you!" Sherry said.

"I never KNEW someone so stubborn! 'Havaii' is how it's pronounced!" he replied.

And so it went, all the way to the vacation. As they got off the airplane, they passed by a man. Morris abruptly stopped his wife and turned to the man to ask, "Now that we're on the island, you can settle an argument between my wife and me. Is this 'Hawaii' or 'Havaii?'"

"This is Havaii," the man replied.

"Ha!" the husband gloated to his wife. "See, didn't I tell you never to argue with me?"

As they began to walk away, Morris turned back and gave the man a hearty "Thank you!"

"You're Velcome!" he called back.
