It's so silly. This old London double decker bus gets up on its front legs and roars. Or should that be groans.
Called London Booster, it's in front of the Czech Olympic headquarters in London and is meant to inspire the Czech athletes to bring home the gold. Mainly it is making everyone giggle.

Czech artist David Cerny created the loveable monster. He bought the bus, circa 1957, in Holland and attached two gigantic electrical arms which lift the body of the vehicle up and down.
