Okay Ladies and Gens, here's the deal!

Take your hands off the mouse and keyboard and grab your shirt! Yes, grab it! Then lift it up over your head. Then look down and see if you have an inny or outty belly button.

Wait, that's not it, now run to your parents, siblings alike, sons and daughters, nieces and nephews and pull up their shirt, rub their bellies and see if they have innies or outties!
