I think it's the 20ft extension cord I have my computer plugged into (shhh don't tell OCZ).
I'm living in an apartment that the university gave me to me at a reduced rate because they ran out of dorm rooms. The complex is going to be torn down within the next 2-3 years and there are no grounded power outlets in my room. So I have to run an extension cord from one of only two grounded outlets in the apartment.
