This comparison of Brits and Americans looks so staged it might as well be a scene from a Richard Curtis film, but it's 100% real.
Ahead of the women's 4x400m relay final at the World Athletics Championships, the eight teams treated the watching fans to their party-pieces.
You might imagine the Americans would be uber-confident compared to the shy and awkward Brits.
Well you'd be right, but it's somehow even more extreme than even we imagined.
The USA ended up taking silver after that effort, which looked like something straight out of Charlie's Angels.
They were comfortably ahead of the third-placed Great Britain team- maybe it is all in the preparation.
