Oh god yes. I used to work with one. We called him "Magnet man" due to his amazing ability to screw up computers purely by being near them.

I kid you not.

We once asked him to drop a package off to one of our customers as he was going to be driving past. Next thing we know he's on the support phone back to base because the machine we had there died the moment he walked through the door to drop the package off. He swears he didn't touch it.
