Showboating can be a cruel mistress in sport.
It looks great when you do it right, like doing skills at the end of a football game to waste time or producing trick shots when you're so far ahead in tennis.
Get it wrong, though, and it can be very embarrassing, as Bath's Freddie Burns discovered during Saturday's Champions Cup match against Toulouse.
Toulouse were winning 20-22 with five minutes remaining when Burns broke free and looked certain to score a try.
It would have put Bath 25-22 ahead, while a successful conversation would have given them a comfortable five-point lead.
Burns was so confident of scoring that he kissed and patted the Bath badge on his jersey and smiled as he ran into the in-goal area towards the posts.
But before he could put the ball down, Toulouse's Maxime Medard came from behind and knocked the ball away to leave Burns red-faced.
The 28-year-old's reaction said it all as he collapsed to the ground in a heap with his hands on his head. He couldn't believe what had just happened.
And neither could his teammates, with one Bath player throwing his arms in the air and angrily tapping Burns on the head as he ran past.
Check out Burns' blunder in the video below.
So poor from Burns. He should have known better than to showboat so late into the match and rugby fans have zero sympathy for him as a result.
Tom Homer replaced the Englishman moments later to play the rest of the game, with Burns left distraught and needing support from his teammates.
That's one mistake he'll never make again.
