Not so much in the 'out-smarted' vein, but in primary school, I was responsible for setting up all 10 of our computers (which we used for something called Success Maker). This is at about 10-11 years old.
A year or so later, my old science teacher drove past me walking home from secondary school, and I kid you not, SCREECHED to a halt. She asked me if I wouldn't mind going with her to fix a few of the computers that hadn't been working for a few weeks. Sorted them out within an hour of arriving!
Felt pretty pro for my 12 year old self, knowing more than the adults.
