Microsoft actually has some humor

The Super Genious Blog has discovered something rather funny. In the preferences folder, some of the files have the Excel preferences icon on them (if you have Microsoft Office). The Excel preferences icon says:

Can you read this

I don’t think so

So, Microsoft thinks that they’re funny, eh? I wonder who it was who made that icon, and I wonder what happened to him?
Update! Every Microsoft preferences file has this, including Word, PowerPoint and Enterouge. (Thanks to Andy for that peice of info.)
