Here are simply mindless puzzles to drive your friends nuts!

1. Johnny: jump one finger to another saying : “Johnny, Johnny, Johnny, Johnny,” then slide from your pointer to your thumb and say “Whoop” do this from your thumb to your pointer saying “whoop” and go back saying johnny. then VERY subtly cross your arms. Your friends will obsess over getting the johnny’s right that they won’t realize all you have to do is cross your arms.
2. Say: If this is a box(make something with your fingers) and this is a box (another shape with fingers) is this a box ( another shape ). It actually has nothing to do with the shapes, but if you say: “Listen, Listen…” then the answer will always be yes and if you go right into the answer will be no.
3. The rock: Make everyone in the circle pass around a rock saying: this is a…. [something] when they do say no. unless of course they said “um” first then it’s correct. They will spend the whole time finding out a pattern to the words they won’t notice you’re saying “um” first.
4. Green Room: You’ll say “only certain things can enter the green room. An egg can, but a chicken can’t” allow your friends to take turns guessing items. You’ll tell them if it can go into the green room. Although they’re looking for a certain meaning to the items, Any item with a double letter in it like the two g’s in in egg. Simple right?

I may find more out later.
