My favorite to as a child would have to be legos. I use to get the huge sets every year for my birthday and they were awesome. I got things like a castle or the set to build an spaceship prison for aliens. But after a while all of my lego sets got mixed into one big box of legos. Then I would build these huge crazy looking house that were like two feet tall. Then as a game I would dump all of the legos on the floor and try to walk a crossed them like I was walking on hot coals. And it felt like that because legos really hurt when you step on them.
