Oh shit yes, my brother and I used to build with legos when we were really little, put them aside for Nintendo and then returned to them to make cars to smash together when we were 11 or so. We were either not that competitive or not that good at it because it took our redneck (positive) cousin to build The Tank for us. It was roughly the dimensions of a building brick with wheels attached. It was hilarious to watch it make short work of all of our previous cars one after another.
