I really don't get what's so fun about planking
If you do it for people to look at you weird- congratulations, you now have tens or hundreds of people thinking you are mentally handicapped. I don't see how that's fun.
Hell, even Cone-ing is better than this.
Never said it was cool.
But its fun to annoy people.
I don't see how it would "annoy" people. It would make them think you're handicapped and incapable of being in public, then they'd walk away and continue their day.
