Take one faux-scientist in a lab coat and bow tie, pair him with a trio of low-rent Supremes wannabes, add a Casio keyboard drumbeat, and then get everyone involved to rap—yes, rap—about why you should upgrade your PC to MS-DOS 5.0. It's five minutes of your life you'll never get back, and just one more crime against humanity we can lay at the feet of Microsoft. Honestly, there is never justification for musically bragging about freeing 45K of memory, graphical shells, or Undelete. Never. Found via my buddy Lizard's blog.
