Cameron Menzies lost his head and smashed up the water table following his shock defeat to Charlie Manby at the World Darts Championship.
The second game of day five's afternoon session of the World Darts Championship saw Menzies face Manby.
And Monday's round one game produced a thrilling result as Manby beat Menzies 3-2 to secure his spot in the next round of the competition.
After Manby threw the winning dart, he wheeled away in celebration as the Ally Pally crowed erupted.

The 20-year-old returned to the oche to embrace the Scot, who could be seen throwing a series of uppercuts at the water table in a moment of madness.
Referee Kirk Bevins walked over to Menzies asking him to calm down.
He eventually shared an embrace with the youngster before walking off the stage.
The crowd booed him as he departed, with the player appearing to have a 'very bloody' right hand, according to journalists at the event.
Sky Sports commentator Glen Durrant said Menzies will regret his outburst 'for the rest of his life'.
"It wasn’t the ending we all want to see," he said.
"I’ll keep it short and sweet: for Cameron Menzies, I think he’ll regret that for the rest of his life. It was not a good watch."
Speaking after his round one victory over Menzies, Manby told Sky Sports: "It was a good feeling and getting settled on a stage where I've never played before.
"I'm glad the Shanghai finish went in."
He added: "This is 100% the greatest thing I have ever done in darts."
Manby, who was making his World Darts Championship debut, hit five 180s and averaged 90.62 in his victory over Menzies, who had an average of 91.99.
He has been backed to challenge Luke Littler at this year's tournament, having already smashed his rival's record on the Development Tour.
The Huddersfield lad racked up an impressive 130.70 average on the Winmau Development Tour in February.
It was the best in the tour's history, obliterating reigning world champion and good pal Littler's record of 115.22.
