There are people that have qualifications comming out of there ears and are complete idiots (i.e. any politician).
Like.. a large chunk of the A+ class I "studied" with.
One guy was so bad that when he was handed a PC with the heatsink detached (and...sitting on the bottom of the chasis, he couldn't spot what was wrong, even turned the PC on.
We sat for a full 5 minutes behind him saying things like, "Dude, I can smell something burning!" but to no avail.
I ended up programming a GUI that replicated windows 2000 but had "<x> has been detected near the machine, so your active desktop has been disabled" and "No applications are suitable for use by the current user"
Daft fucker.
Luckily he didn't pass, but he survived the whole year!
