1. Wasn't this on "Jackass"?
Vehicle: Giant Shopping Grocery Cart
Complex Says: This is actually a motorized vehicle. In fact, it's powered by a Mustang engine (though the owner doesn't specify which one), and it will allegedly go up to 100mph. To drive it, you have to be in the child seat at the front of the cart. We're pretty sure it isn't street-legal--after all, it's not one of those carts that has a seat belt for your child. You can apparently fit up to 25 people in this cart at a time, in case you were wondering.
