Rambo was here for a visit last week. Apparently his owner was in the hospital. You may remember that he's short; I heard FatBoy say something about "Welsh Corgi" but he didn't look like grape jelly to me.
Anyway, he has some weird habits. One of them is his reaction when FatBoy presses that button on his desk, many times a day. I think he calls it a KVM Switch, but I can't see up there, so I don't know what it does, other than make a little sound which drove Rambo crazy every time he'd press it. And, Rambo never learned - he'd bark like crazy every time the switch was pressed, which often interrupted my cat naps.
Honestly, I'm glad he's gone. Now I can get some uninterrupted rest.
