When I'm board I like to play games (like most normal people do) However one of my favourite game is called pokies.
What you need
•Someone to annoy
•a finger
•place to run or hide.

What to do
Go to the person you are trying to annoy. Stand or sit next to them for awhile then poke them. Say sorry pretending it was an accident and keep doing what you are doing.

About one minuet later poke them again to show them something like
"Hey check out the blue sky."
That will really annoy them.

Wait another few minuets then poke them again but this time run off. Come back and keep doing it until they go insane.
(Or slap.) one or the other is fine.
