Alphabets

This one was from February 2012:

Bryan: Are you guys ready for the coffee news trivia?
Me: Sure
Bryan: How many letters are in the Hawaiian alphabet?
Mama Chan: H-A-W-A-I-I
Me: (laughing my head off/shaking my hand furiously) No no no no no no! That's not what he meant!
Mama Chan: What? What's wrong?
Bryan: (no words - laughing so hard he's coughing)
