Bwahahaha, that's the funniest thing I've heard in a long time. I hope this 'IT guy' is not in charge of anything important at your work... otherwise I bet you have loadsa problems
Seriously, this guy is obviously stoopid, which begs the question how he got the job. There was an interesting discussion in Computing recently about there not being any real standardised certification that IT people can take, as opposed to a mechanical engineer, doctor, lawyer, etc... This guy sounds like a prime example of this.
