Not as good as I would have liked, but not bad.

Who’s Yoda?

As someone who has never watched a Star Wars movie, I am nonetheless astonished at your query, but in a pleasant way.

Yoda: a character in the Star Wars films known for dispensing ersatz Confucian backwards-phrased wisdom:

Powerful you have become, the dark side I sense in you.

Once you start down the dark path, forever will it dominate your destiny, consume you it will.

Welcome you are.

We need a talk like Yoda day.

A talk like Yoda-o day we need-o.

I’m already annoying myself.

25%, which, given that there are four possible answers, is the same as a random generation of responses would score. Very dumb I feel. Perhaps Budweiser is worth another try…

Unless you’re washing you hair, no. No it’s not. In fact your sentence fragment is at least as baffling as “perhaps tearing off my ear is worth another try...” would have been.

It seems there is some dispute over whether Talk Like Yoda falls on May 21st or May 22nd or potentially the weekday nearest May 21st. 

According to this site it was originally going to be on the 21st, but the first year they were going to have that would have been a Sunday, so they moved it to Monday.  Some people have thus kept it on the 22nd.

Purists, like TalkLikeYoda.com are sticking with the 21st. 

I can’t find a Wikipedia entry addressing this, so I’m gonna assume you can pick either (or both) for your personal observance.
