I think I get it because of Weird Al's 'All About The Pentium'-
You gotta be the dumbest newbie I've ever seen
You've got white-out all over your screen
You think your Commodore 64 is really neato
What kinda chip you got in there, a Dorito?
You're usin' a 286? Don't make me laugh
Your Windows boots up in what, a day and a half?
You could back up your whole hard drive on a floppy diskette
Got a flat-screen monitor, 40" wide
I believe that yours says, "Etch-A-Sketch" on the side
In a 32-bit world, you're a 2-bit user
You've got your own newsgroup, alt.total-loser
Where'd you get your CPU, in a box of Cracker Jacks?
