Substitute Florian Lejeune scored twice in added time as Newcastle snatched the unlikeliest of 2-2 draws at Everton to spoil Moise Kean's celebrations after his first goal for the club.
The Toffees were cruising deep into four minutes of stoppage time at the end of the second half thanks to goals from Kean and Dominic Calvert-Lewin but threw away the three points with some comical defending which stunned the majority of Goodison Park.
Steve Bruce's side were barely in the game - they had managed just one shot on target - when Lejeune flicked home an overhead kick.
There were possibly 90 seconds left at that point and the home side should have killed off the game, having controlled so much of it, but panicked and when the visitors pressed forward.
Lejeune forced home his second in a goalmouth scramble.
It ruined what should have been Kean's night after the striker finally produced the performance Goodison Park had been waiting for.
Barely a month ago Kean, memorably, was taken off by caretaker manager Duncan Ferguson just 19 minutes after coming on as a second-half substitute at Manchester United in what was arguably the lowest point of his short Everton career.
But the 19-year-old Italy international has been given a chance to impress by new boss and compatriot Carlo Ancelotti and marked his first back-to-back Premier League starts with that all-important goal in his 22nd appearance since a £27.5 million move from Juventus in the summer.
However, it was Lejeune who grabbed the headlines on a dramatic night at Goodison.
Southampton continued their revival with a 2-0 victory away to Crystal Palace which saw them leapfrog the hosts and make it six wins from their last eight games in all competitions.
Nathan Redmond and Stuart Armstrong were on target for Ralph Hasenhuttl's team, who are now 10th in the Premier League table and eight points ahead of the bottom three.
Palace's five-match unbeaten run in the division came to an end in disappointing fashion with Roy Hodgson's men unable to cope with the energy or movement of the visitors at Selhurst Park.
Irish striking duo Michael Obafemi and Shane Long were both handed starting places, with Saints top goalscorer Danny Ings rested ahead of the FA Cup clash with Tottenham at the weekend.
Southampton took the lead on 22 minutes when Jack Stephens passed into the path of Redmond, who impressively turned away from Martin Kelly and let fly from outside the area - giving Vicente Guaita no chance and finding the top corner for his fourth goal of the season.
They doubled their advantage in the 48th minute through Armstrong.
Redmond found the Scotland international and he curled in from 25-yards to hand Hasenhuttl's men a decisive two-goal lead.
Tyrone Mings' last-gasp winner lifted Aston Villa out of the relegation zone and ended Watford's recent revival in dramatic style.
The defender grabbed a fortunate deflection on Ezri Konsa's shot in the fifth minute of stoppage time with virtually the last touch of the game to snatch a 2-1 victory.
Douglas Luiz had earlier come off the bench to level in the second half, just as Villa looked like they would be plunged into further trouble.
It cancelled out Troy Deeney's opener as Watford's six-match unbeaten in the top flight was ended.
Victory - just Villa's third in 11 Premier League outings - moved them up to 16th and two points clear of the drop zone while the Hornets slipped back into the bottom three.
Bournemouth eased some of the pressure on manager Eddie Howe with a crucial 3-1 win over Brighton.
The Cherries' woeful recent form has raised questions about Howe's future for the first time in his 11 years in the dugout.
But strikes from Harry Wilson and Callum Wilson, either side of a Pascal Gross own goal, secured a much-needed win to lift Bournemouth to 18th, level on points with West Ham and safety.
