The Mandarin Chinese word for “I” is “Waa” with a falling/rising tone.  Grasshopper and I had trouble remembering the tonal component, (as Americans often do).

Until I remembered Jon Stewert, and his trademark response to some woefully stupid or incomprehensible action/statement/position by a politician or media talking-head:

“Whhaaaaaaa?”

Forgetting the tone of that word is no longer a problem.

Jon Stewart.  Cute, funny, impeccably well-dressed, and the best darn mnemonic device out there for the Mandarin personal pronoun.

There should be some sort of award.
