Dilbert: We need to upgrade some of our servers. Coworker: That's dumb. We upgraded two of them last week. Dilbert: Right now we need to upgrade the rest of them. Coworker: Then why did you say we have to upgrade all of them? Dilbert: Well, I didn't. But I think we all agree on what needs to be done. Coworker: Not if you insist on upgrading the servers we already upgraded last week. Dilbert: Gaaaa!!! Kill me with a comet!!! Coworker: Does he ever say anything that makes sense? Wally: There's no way to be sure.
