Monk Must Die

Okay, I like webisodes of things, not gonna lie about it. But the problem is, so does Munch. The last Monk one he saw had Monk rearrange a keyboard alphabetically. He thought this would be funny to do to me. I spent yesterday fixing that.
Now, I figure the easiest solution would be to punch him in the face. It seems inelegant, though, so I have a few options.
1) I could unplug his mouse connections. Unfortunately, I think he's expecting it.
2) I could set his computer to Cyrillic - he'd expect that, too, seeing how we did it to Goren. I might add if the person you're pranking can type in Cyrillic, it isn't funny.
3) I could sign him up for some truly horrid porn - but what if he likes it and tells me about it? Not good.
4) I could put a tuna sandwich in his processor box.

I'm thinking 4 and I could punch him in the face as a distraction, so he doesn't suspect me straight off the bat. It's not the best plan, but it's what I have so far.
