The pressure of a football game can make players do strange things in the heat of the moment.
We all remember David Beckham kicking out at Diego Simeone at the 1998 World Cup or Newcastle United teammates Kieran Dyer and Lee Bowyer both being given their marching orders after fighting back in 2005.
But former Manchester City striker Edin Dzeko might have just trumped even that for the most bizarre red card we've ever seen.
The striker was in action for Bosnia-Herzegovina on Sunday evening in his country's World Cup qualifier against Greece.
And, although the now Roma forward hadn't got himself on the scoresheet, thinks were going well over the first 80 minutes as Bosnia-Herzegovina held a narrow 1-0 lead going into the final 10 minutes.
Then the red mist descended.
Dzeko was involved in a coming together with Sokratis Papastathopoulos that began when the ex-City striker appeared to be tripped by his opponent.
He was left on his back on the pitch as Papastathopoulos stood over him - a situation Dzeko did not find amusing to say the least.
But, rather than bite his tongue, get up and get on with the game, Dzeko took the rather extraordinary decision to respond by pulling down the shorts of the Greek defender.
We're not sure there is a specific law against pulling your opponent's shorts around his ankles but, as you might expect, the referee didn't look too kindly on Dzeko's antics.
Having already been booked in the first half, the former Premier League striker was given his marching orders after picking up his second yellow card.
He did manage to drag one Greece player with him, though, after the big brawl that followed his playground tactics led to Kyriakos Papadopoulos also being sent off.
It was Greece who had the last laugh, however, after they equalised in the 90th minute to rob Bosnia-Herzegovina of what would have been a crucial three points.
