Believe it or not, WWE can be a frustrating business for the superstars involved, as well as the WWE Universe that watches the events at home or live inside the arenas.
WrestleMania is WWE's biggest show of the year, and with it comes the added expectation to put on a fantastic show that should blow the fans away.
After the Royal Rumble last night, WWE aired another episode of their special 24 documentary series, this time covering WrestleMania 34 which took place in April last year.
The main event of WrestleMania in 2018 was Brock Lesnar vs Roman Reigns for the Universal Championship, but it didn't go down well with the fans watching at home or inside the Superdome in New Orleans.
Lesnar won the match, but due to the reception he received, when he came back to the Gorilla Position, he launched the Universal title at Vince McMahon.
In response, the chairman appeared to swear at The Beast, but the clip confirms as well that even the superstars involved in the match weren't happy with the way which it finished.
It also confirms as well that the almost year-old rumour about the altercation between the two is indeed in fact true.
Despite the raw anger at this moment, it seems as though those involved were able to work things out, as Lesnar is still with the WWE today.
One thing for sure, nobody can question the Universal Champion's passion for WWE, as all his emotions are shown in this short clip, exhausted and frustrated after working himself to the ground in the ring.
It looks as though The Beast will be walking into this year's WrestleMania as Universal Champion as well after what happened at the Royal Rumble last night.
Brock defeated Finn Balor via a Kimura lock submission on Sunday to retain the Universal title, and he'll likely defend the title again at WrestleMania 35 later this year unless he surprisingly loses the title between now and then.
As for his opponent for The Showcase of the Immortals, that will likely be Seth Rollins after he won the men's Royal Rumble in the main event of the show.
This could also possibly be Lesnar's last feud in WWE as well before he leaves the company to pursue UFC again.
