How to convince boys to put up their legos away!

Hey Guys! Its The Beauty Queen and today I want to show y'all how I convince my brothers to put away there legos cuz if you can't tell when you step on them they hurt! + Who wants boys to have a messy room with legos every where? I know I don't. So heres the trick if your kids keep refusing tell them they will get an award such as money , small toy, trip to mcdonalds or something whatever you think they deserve and if your going to reward them make sure they have been on their best behavior.
