A small (18") working fire truck, hoses and all.
Christmas time, out in the back yard, starting grass fires so I could put them out.
There was one of those at the local five-and-ten that I wanted so badly I could taste it. I didn't get it and it has haunted me ever since. I used to look on ebay and saw that they were selling for quite a bit of money. I would have bought one if I had ever seen one that was complete and in good working order.
