Imaginitive, creative, ingenious and entertaining - but not really inventions as they have no practical applications!

I would dispute the world's fastest toilet claim, since trains have toilets and some of those travel at 150 - 200 mph - e.g. in France. Long distance motorway coaches have toilets too, and they do 65 mph. And of course, airliners also have toilets and they do 500 - 600 mph!

World's fastest mobility scooter? Well, go karts are really just sporting versions of the mobility scooter concept and they can go faster than 71 mph!

The pulse jet bike, on the other hand does have something going for it - motorists would give it a very wide berth when following or overtaking it.
