Grocery carts are one of the greatest inventions of all time. They have tons of uses. Races, travels, banging into -blam!-ss cars, all kinds of sports, and even carrying groceries!! My favorite is sports. I played basteketball with them 2 or 3 days ago. It was fun. I dislocated my shoulder. Then popped it back in. Then kept playing. (after a five minute break, of course). Another thing I did was have my friend push me around (mostly through intersections) with me pretending I was dead or hurt badly. I got in a really wierd position so it looked like my leg was turned around. The looks we got were priceless. This is completely random and has nothing to do with anything besides grocery carts.
