PEBCAK*

Actually, the commonly accepted acronym is, as Jenna stated, 'PEBKAC'.  (Problem Exists Between Keyboard And Chair)  I've seen it reversed in such a manner, but to anyone who's been around computers for the better part of microcomputing history (Yes, I realize I'm still young, but everything before my time with it was neither 'Better' nor 'micro'. ) will tell you the acronym originated in such a manner, and will puritanically defend the correct order of the words.
