James Corden and Matt LeBlanc go head-to-head on children's scooters.
Jumping on the children's scooters, the competitive duo couldn't contain their laughter as they prepared to take off in a Top Gear spoof for Corden's the Late Late Show.
The segment, called Bottom Gear, saw the pair race down the hallway on tiny scooters and tackle obstacles such as silly string and mini ramps.
It looked like it would be an easy win for Corden but Top Gear presenter, LeBlanc, managed to sneak up behind him and it was a tense, neck-and-neck race towards the finish line.
