Some folks like to take their time on the can. Not Paul Stender. When the 43-year-old former pit mechanic feels the need for speed, he straps himself into his jet-engine-equipped toilet and roars off, trailing flame. Stender was running superfast snowmobiles on the drag-racing circuit when he saw his first jet-driven funny car. He liked it so much he bought one, and started building his own outlandishly overpowered vehicles: a jet motorcycle, a jet pickup, a jet school bus. Then one day at a show in Texas, he saw a windstorm blow portable toilets across the tarmac, and it was Newton's apple all over again.
