This is video of a French pole vaulter, Renaud Lavillenie, having a little bit of a tantrum, after receiving a red flag at the European Indoor Championships.

Lavillenie, a gold medalist who thought he'd just achieved the second-highest pole vault in history at the European Indoor Championships, was upset after it was ruled that he tipped the bar off its pegs, even though the bar ended up perched on a ledge rather than falling.
