Surely if you've already gone far enough to pick up a keyboard handbag and keyboard shoes, you're cool enough to go all out and get yourself a pair of keyboard boxers. After all, they're only $16 (plus shipping), so what's stopping you?
We don't guarantee that this particular garment is made from actual keyboards, though that may be a relief in this case. And we could do without the sets of grayed keys that spell out "Computer Geek." I mean, we get it, thanks. Anyway, if you're determined to eventually dress like the PC equivalent of the Riddler, these should get you well on your way.
