I've got a good one -

First do one that involves nuclear bombs for sure. Then you need to find something that'll trick your friends into thinking something is going to happen soon. Probably with a message from someone first and then a siren of some sort that tricks them into thinking it's real.

Either that or something you can make that tricks them into thinking it'll happen.

Hope this helps.

Tell him the Mayans made a slight mistake and that the world will end on Jan. 21, 2013. Then get your atom bomb and set the timer for 1/21/2013. Leave it next to his bed.
