Nick Kyrgios' furious temper tantrums featured heavily in a dramatic loss to Rafael Nadal when they met in the quarter-finals at Indian Wells.
Nadal won the wild showdown 7-6 5-7 6-4 but some angry outbursts provided as much entertainment as the actual tennis.
After being broken in the third set, Kyrgios unleashed on chair umpire Carlos Bernardes for not keeping the crowd quiet, especially when yelling out between first and second serves.
"How long are you going to let that s**t go on for? How long? How long? How long, bro? How long?" Kyrgios yelled.
"If you did something about it before, maybe it wouldn't have happened.
Bernardes defended himself, saying he had told the crowd before to keep quiet.
That outburst came after Kyrgios dragged Hollywood star Ben Stiller into his grievances in the third set.
The actor was sitting in the front row behind the baseline when someone in the crowd ticked Kyrgios off, perhaps suggesting where he should serve or what he should try to disrupt Nadal.
The heckler replied "no" when Kyrgios asked "are you good at tennis?" before the tennis player drew on a real-life example and used Stiller to make his point.
"Exactly, so don't tell me how to play. Do I tell him how to act?" Kyrgios said as he pointed at Stiller.
"Shut the f*** up," the wild child uttered later.
It was a shame to see Kyrgios implode because he showed glimpses of the talent that can give even the world's best players a real fright.
He peeled off some scintillating ground strokes and broke early in the opening set, letting out a loud roar as he hit his stride.
An underarm tweener serve — similar to the one he pulled off at this year's Australian Open — didn't quite work for Kyrgios this time, as Nadal responded with a forehand winner, but everything else the 26-year-old was doing paid off as he maintained his break advantage at 5-3.
Kyrgios was seen complaining to his team that Nadal "is so lucky" as the 21-time grand slam champion stayed in the hunt for the opening set.
Kyrgios revved up the crowd when he won a crucial point in the next game as he made Nadal work for absolutely everything before the veteran held serve and edged ahead 6-5.
From here, the world No. 132 started to lose the plot, smashing a racquet and receiving a code violation — before offering his damaged equipment to a boy in the crowd.
Down 15-30, Kyrgios let everyone in the crowd know how unhappy he was but still he held on to send the set to a tiebreak.
Nadal was ruthless though, zipping to a 5-0 lead as Kyrgios' temper got the better of him, repeatedly complaining throughout the breaker and having a go at someone in his player's box.
At 0-6 Kyrgios received a point penalty for another code violation — because of an audible obscenity — to end the set in anti-climactic fashion.
"Ten thousand people who want to watch tennis here and you are the only one screaming like crazy," the official told the spectator as he called for quiet.
But nobody could drown out Kyrgios' self-admonishment. "What am I doing?!" he yelled during the second game of the second set, as the match continued to slip away.
However, Kyrgios started to find some calm and the tide turned. He went up 4-3 when he trolled Nadal by acing him with an underarm serve the Spaniard had no chance of reaching because he was so far back from the baseline.
Kyrgios embraced the momentum shift and secured a break then closed out the second set 7-5 to send the match to a decider, roaring loudly and encouraging the crowd to fire up in support.
He maintained the rage in the third set but missed a golden opportunity to break early as Nadal struggled on serve.
It was all over after his final blow-up at Bernardes, as Nadal kept his cool to progress through to the semi-finals.
