I read the Dilbert comic today, and liked it so much that I had to mention it.

Carl: Although I’ve been fired for gross incom­pe­tence, I’m profes­sional enough to train you before I leave.
Dilbert: Don’t bother. I’ve already coded a Java app to do every­thing you do.
Carl: Every­thing?
Dilbert: Except for the incom­pe­tent parts.

What I like about Dilbert is that he is one really smart guy in a mad mad world.
