Scrum-half Dan Robson scored a very controversial and sneaky try as Wasps smashed Worcester 47-24 to reach the 2019/20 Gallagher Premiership final.
The try, which caught everyone off guard, had the referee have his back to the attacker while speaking to the defence.
A lot of fans on social media were baffled that the try stood with the referee the target of most the criticism.
But wasps legend Andy Goode was on hand to put them in their place.
Wasps will now face the winner of Saturday's second semi-final between Premiership table-toppers Exeter and fourth-placed Bath at Twickenham on Saturday, 24 October.
All Black Malakai Fekitoa's try and and two Jimmy Gopperth penalties put Wasps 13-0 ahead before Aussie speedst Luke Morahan's try for Bristol.
Another Gopperth penalty and a try from the impressive Jack Willis saw Wasps have an 18-point lead at half-time.
Harry Thacker got a try back but Dan Robson, Zach Kibirige and Matteo Minozzi saw off Bristol, before Harry Randall and Max Malins went over for late consolation tries.

5 people who should avoid reading Joe Marler’s new autobiography
Due to him forever knocking everything over with his backside, the biggest in world rugby, Marler joked 'your ass is like a permanent slosh bucket.'
Long story short, he hated it but is still known as 'Slosh' or 'Slosh bucket' to this day in England training/
2. Gavin Henson
Despite this being another rather funny story from Marler, it also shows the ego of Henson in 2005 was off the scale. Being told to hurry up with his hair by his captain Gareth Thomas, the playmaker showed his skipper little respect.
Henson's reply to Thomas was: "Alf, your mother and father have come to watch you play today, but there are 72,000 out there who have come to watch me."
3. Olly Kohn
One of the hands down best stories from the book comes from a wet and windy away game in Biarritz where Marler thought he might 'freeze to death in a cloud of garlic breath and BO.'
A desperate idea saw the prop piss himself, and after being sussed out by teammate Kohn, the lock joined him, 'piising their pants in unison in an effort to survive.'
The two then promised to never speak about the incident, which Marler apologies for breaking in his book by simply saying 'sorry mate'.
4. Jonny May
This isn't necessarily a negative story about the speedster, but having the fact you take part in WWE like wrestling in your underpants published to the masses probably isn't ideal.
Marler tells a wonderful story of how their epic one-on-one match from behind closed doors was discovered by 2003 World Cup winner and then England coach Mike Catt in 2013.
This resulted in the pair having to wrestle in front of their teammates with May coming out on top after Marler was forced to start on his knees due to his weight advantage.
Marler went onto say: "It was always Jonny who usually tapped out. He was incredibly fit and strong and his wrestling skills were awesome, but being the much chunkier bloke I beat im every time."
Later on, Marler tells the story of May scoring a try for England U20 with his ass off in incredible detail, saying at one point: "I mean, it wasn't just a bit of bum crack or half a cheek poking out. This was full moon."
5. Dwayne Peel
The loosehead prop tells a wonderful story of how the legendary Wales scrum-half, who won 76 caps between 2001 and 2011, got a taste of his own medicine when his pranks became too much for some of his teammates.
"He'd tested his teammates' patience by putting bikes and beans in their (Wales squads) beds." wrote Marler.
"The lads decided to retaliate, with one of them borrowing a sheep from a local farmer and leaving it in Peel's hotel room.
"The flea-ridden sheep had pooed on the carpet before Peel discovered it, and legend has i he was itching for days afterwards."
