It was an inglorious moment for Michael Schumacher on this day at Monaco in 2006.
The Ferrari driver was found guilty of deliberately obstructing his colleagues in the final minutes of qualifying.
The German, who was on provisional pole but with other drivers going potentially faster, purposefully parked his car at the exit of Rascasse, pretending a brush with the barriers and stalling his engine.
The yellow flags came out and the field were denied their final effort.
The German later defended the maneuver, explaining to an incredulous audience that his ultimate lap 'had been a bit too much'.
The stewards were unimpressed and stripped the seven-time world champion of pole, sending the Ferrari driver to the back of the grid.
