on why you shouldn't answer your work phone after hours

 I answered my work phone at 5:05pm and ended up working until 9pm.  

In other news, the HTC phone commercials re-ignited my love for Nina Simone's "Sinnerman". Man, this is such an amazing song.

And so is this, by the way:  Watch to the end, when Letterman is so tickled with the awesome performance that he asks them to continue for a little longer. 

As someone on Reddit said: Go on, rock out with your cock out!
