I thought this, which I just got in an IM, was pretty funnyโ€ฆ and thereโ€™s something to it:

The problem with tech guys is that they are this generationโ€™s auto mechanics. They tell you whatโ€™s wrong, and there is no way to know if theyโ€™re full of it or not.

I hope weโ€™re raising more auto mechanics though, because I didnโ€™t take shop class. (Do people anymore?)
