Here's something totally normal from Brazil's Série A. Sport Recife defender Tobi gets booked during the first leg of the Campeonato Pernambucano final (a regional championship) and, when asked by the referee to turn around so the ref can see his number, performs the moonwalk. While American audiences may find the moonwalk impressive, to the dance-mad Brazilians we're sure it looked like someone performing the robot.
