Red Bull soap box racing

I saw this today on the tellybox, from Cork, Ireland, looks like a good laugh to me, one cart was made up to look like a breakfast roll, among many others , an altar with wheels, which got a Holy water blessing from the priests at the top of the steep hill .
If you would enter the one in London in the summer, what would cart would you design and why ?
It seems that no brakes are allowed on the carts .
Carryfast cart, with a towing trailer of encyclopedias maybe ?
Dipper Daves cart, to resemble an Anne Summers shop ?
Dozys cart , get out of the way, i am not stopping for anyone ?
Trucker Jay ,with giant L plates ?
Switchlogic cart, towing a Tesco trailer at speed restricted 12.9 mph ?
Toby cart, a stuffed manequin with the Mayors daughter written on the front ?
