Apparently Sunday March 22 was "International Talk Like William Shatner Day". 

 How can something as important as this come and go without me noticing?  I am forever shamed, and will go out of my way to talk like William Shatner extra hard next year.

(Note: This is likely the first of many Trek posts that will appear between now and May 8.  Sure, you don't care now, but when you are transformed into a Trekker by Mr. Abrams in t-minus two months, your gonna look back and regret missing Talk Like Shatner day too.)

 UPDATE: Maurice LaMarche, voice actor, creator of Talk Like William Shatner Day, and self describe third-best Shatner impersonator, explains how to talk like Shatner in this billiant video.
