You have obviously not been knocked on your but by a capacitor 
that is totally disconnected from the circuit and in storage. 
There is a reason that high capacity devices are shipped and 
stored with a shorting wire across the terminals.  They will 
spontaneously charge! 

If you don't believe it, get a multi KV 1000 uF oil filled cap 
and leave it set on the floor for a year or two then grab the 
terminals (don't do this at home and without medical help in 
attendance).
