I'm not kidding:
I was knitting at my computer desk while surfing the interwebz when I heard a *slurp* and looked down to see a piece of yarn attached to the project I was working on sticking out of the back of my computer.
I may need to clarify a couple of things here. One, there's a huge open space in the back of my computer due to the fact that I have a slim-sized motherboard in a full-sized chassis. Two, one of the case fans is right next to that lovely hole. Three, my computer is currently sitting next to my chair because I don't want to shove it in the corner it belongs until I get the switch I need to complete my setup (and of course I haven't bought the switch yet).
So I guess it was a matter of time before it ate my yarn.
Luckily for me, it only ate the piece left over from the start of my project and the top of the chassis comes right off. So I was able to cut the yarn off the project and open the computer up to unwrap the yarn from the back fan:
Now I know to keep my yarn away from the damn thing. Oye.
