“No but you don't get it, my son is really good at those things, he said he would speed up our Windows machines 10x if I gave him the codes and physical access to the servers during weekends!”
That would be a very bad, very cliche joke if it weren't a true war story (2005, good times). Turns out the 15 y.o. had convinced his father that I was "lame" at my job because I didn't tweak regedit. Important lessons were learned by the three of us that day!
