This is Jolene Van Vugt topping out at 46.6 miles per hour (75km/h) on a kart/bog, setting the new Guinness World Record on a Motorized Toilet. Timed twice over 100 meters in Sydney, she smashed the previous record by 4.3 mph.

Van Vugt described the toilet on her blog stating, "It was pretty gnarly and I had a few close calls with the kart getting a little sketchy at high speeds on the rough, angled, cobble stones out front of the Sydney stadium."

Van Vugt performs in Travis Pastrana's Nitro Circus and holds two other world records, both for back flips on dirt bikes.
