On four successive previous occasions after derby euphoria, Sunderland's bubble was burst by a subsequent defeat.
But Sunderland's fifth loss in-a-row following a win over Newcastle was the most spectacular yet after a defensive horror show saw Sam Allardyce's side butchered 6-2 at Everton.
In a new 3-5-2 system to cope with the absence of injured centre-halves Younes Kaboul and John O'Shea, Sunderland were torn apart with frightening ease at Goodison Park, to undo any good work in the opposite direction.
Sunderland fell two behind against the run of play, yet managed to get themselves level with a pair of quick-fire goals either side of half-time through Jermain Defoe and Steven Fletcher.
But in a spectacular 21-minute collapse, Sunderland conceded four times - including the completion of Arouna Kone's hat-trick - to fall to their heaviest defeat since last season's 8-0 drubbing at Southampton.
Despite the second half collapse, Sunderland's formation almost produced instant dividends in the fourth minute when Patrick van Aanholt picked out Fletcher down the left-hand side of the area.
Fletcher returned the ball to the Dutchman, whose left-foot shot from just inside the area crashed against the near post.
Sunderland were denied by the woodwork again in the 15th minute after an excellent break forwards from van Aanholt, who picked out Jermain Defoe on the far right-hand side of the area.
Defoe's right-foot shot was well-saved by the legs of Tim Howard, before Adam Johnson's scuffed effort on the rebound hit the post.
But against the run of play, Everton broke the deadlock four minutes later when Kone's pass sent Gerard Deulofeu clean through on goal after van Aanholt had failed to track the ex-Barcelona man, while Jones had failed to spot the run.
Deulofeu checked back on the back-tracking Sunderland defenders before calmly slotting it under Costel Pantilimon.
Moments later, Pantilimon had to be alert to turn away Seamus Coleman's shot at the near post.
Everton did double their advantage in the 32nd minute when Kone played a one-two with Romelu Lukaku just inside the area, and was allowed too much room to get a shot away.
There was too much venom behind Kone's left-foot shot for Pantilimon, albeit the Romanian's positioning was poor.
Sunderland were forced into a change before the interval when captain Lee Cattermole limped off with what appeared to be a knee injury, with ex-Everton man Jack Rodwell taking his place.
On the stroke of half-time, Sunderland were given a lifeline when Defoe controlled Coates' ball forward, lifted it over the tackle of Ramiro Funes and hit a fierce shot which took a slight deflection off John Stones and nestled in the far corner.
Five minutes into the second half, Sunderland drew level when van Aanholt crossed right-footed from the left and Fletcher was able to guide a header into the bottom corner.
But Everton regained the advantage just five minutes later when Deulofeu crossed from the right and it bounced towards Lukaku, loitering between Coates and Brown.
Coates took it off the head of Lukaku with his outstretched right boot, and that was enough to deflect it past the helpless Pantilimon.
Everton then restored their two-goal cushion on the hour mark after more awful Sunderland defending when Deulofeu's through-ball completely scythed open the Black Cats backline.
It left Lukaku with a clear run on goal and the Belgian rounded Pantilimon, before placing it into the empty net.
Three minutes later, Everton scored again after Sunderland were ripped apart with frightening ease on the counter-attack.
Ross Barkley strode forwards, squared it to James McCarthy, who picked out the overlapping Kone down the left-hand side of the area and he had an age to lift the ball over Pantilimon.
Kone completed his hat-trick in the 77th minute when he headed unmarked beyond Pantilimon after Coates had nodded off to Lukaku's cross.
The only bright spot in the finale was the attitude shown by substitute Duncan Watmore, who almost grabbed a consolation when his attempted chip was parried by the finger-tips of Tim Howard.
