I think you will get more sympathy than laughs. I cant count the number of 
times I spent hours or days trouble shooting an issue only to discover I fat 
fingered a conf or forget to click a check box.

Once I even plugged an IDE drive in to the cable.....with the system running. 
Now it's a paper weight.

Always give that resounding, "DOH!"
