This mashup of Ke$ha's ubiquitous, unrelenting hit song and classic Star Trek makes two things perfectly clear: 1) The Enterprise was a nonstop party vessel and 2) Kirk/Spock slash fiction will never die. [Topless Robot]
Okay, I admit it: I not only like the mashup, I sorta appreciate the song for its danceable qualities.
If you want to see something really compellingly weird, check out Ke$ha's version of this song that she did live on SATURDAY NIGHT LIVE (probably available on Hulu) a month or two ago. We TiVoed it, and I didn't bother to watch it until Mrs. Overclock (etc.) recommended it.
