A game where I can ruin someone's day?

I'm looking for one of those games where I can absolutely ruin someone's fun to the point where they are screaming at me. Just by dropping by and leaving satisfied by another person's misery.

Something like lighting a person's house on fire in Minecraft or killing someone in Haven and Hearth.

Oh and it has to be free to play.

What is the best gaming laptop?

So I'm thinking of buying a decent gaming laptop(that can at least run Minecraft, GTA IV, Saints Row 3 etc. Smoothly)
Price range is $500-$800

I found thses two links but can't decide.
Please look at these two links and tell me if which do you think is better for the price. And if you know of a better laptop please tell me.

How to light a portal FROM the Nether?

Today, in Minecraft, I pulled a really stupid move. I needed to move my portal, because it spawned in the air. I climbed up to it, and went to my house to get my ONLY DIAMOND PICKAXE. I went back to that cavernous hell that I'm now trapped in, because upon destroying my portal, I realized that I forgot to bring my flint and steel. I'm now stuck unless someone can tell me how to light it again.
