Why won't you just tell me?

So I kept asking Mr. Katohater what he was doing yesterday, mostly to bug and annoy him, and he kept avoiding my question.  He said he was working and when I asked him what he was working on he wouldn't just tell me.  At some point later on when I got bored again that I wanted to annoy him I tried to get a picture of him and his mustache.  This is what I got:

Later I checked out his blog and that is when I found out what exactly he was working on.  NERD!
