Today is William Shatner's 80th birthday. It's hard to believe that Captain Kirk is an octogenarian, and frankly, he seems busier now than he has been in years -- he's actively working on multiple TV shows (one's even on a major network), he's got an autobiography on bookshelves, and the Original Captain even has a YouTube channel. Today also happens to be International Talk Like William Shatner Day (note that the Facebook group is classified as a "Religious Organization").

And although I've posted this video before, I feel compelled to highlight Fear of Pop's classic song "In Love" today -- a collaboration between Ben Folds, a large band, and Shatner doing spoken word. It's wonderful.

Various Shatner impersonations after the jump:
