I liked the look on the face of the poor guy holding the jack. It would be much funnier if it happened in a race though. Just imagine you are Fernando - you finally have a competative car and heading for a podium when you pull into the pits....
Surely can't have been the regular pit crew. The best bit is the rear offside guy trying to fit the 2nd replacement tyre the wrong way round before realising it doesn't go on that way!!
