Marcus Tudgay and Robert Earnshaw both scored twice as Nottingham Forest thrashed east midlands rivals Derby.
Luke Chambers headed in Radoslaw Majewski's cross at the back post to give Forest the lead but Luke Moore fired in off the bar to equalise.
Tudgay headed home crosses from Earnshaw and Nathan Tyson as Forest ran riot, before Earnshaw poked a fourth.
Kris Commons' 25-yard deflected free-kick gave Derby hope but Earnshaw's 12-yard finish wrapped up the points.
Tudgay, on loan from Sheffield Wednesday, began his career with the Rams and Earnshaw spent one season at Pride Park, but there was no room for sentiment as the pair put their former club to the sword and sent Forest to within one point of the play-off places.
The Reds were taking the field for just the second time since November 29 but Billy Davies' side showed no signs of lethargy, with Chambers giving them the lead after two minutes.
Majewski flighted in an inviting corner for Chambers to power home a header at the far post, for his second goal in as many matches.
Forest continued to look dominant, but they were pegged back in the 14th minute as Derby produced a fine goal on the break.
Alberto Bueno burst forward before feeding Moore's clever run and the on-loan striker fired in off the bar from 18 yards.
There was no let up to the high-tempo opening and Earnshaw was the architect as Forest regained their lead 10 minutes later as he twisted and turned on the right before dinking in a precise cross for Tudgay to head in off the underside of the crossbar.
And with three sides of the City Ground still celebrating, they should have been cheering another goal when Aaron Ramsey, making his first competitive start since breaking his leg for Arsenal at Stoke in February, sent Earnshaw through on goal, but Stephen Bywater made a fine block.
Forest's lead was extended when Tyson showed pace and strength down the left and he supplied a perfect cross for Tudgay to head home from 12 yards.
Earnshaw then squandered a golden opportunity within the opening 30 seconds of the second half when he shot weakly when through on goal.
He made amends soon after, however, when he poked home his second of the season after more good work from Tyson.
Derby refused to crumble and kept hopes of a comeback alive two minutes later when Commons' 25-yard deflected free-kick wrong-footed Lee Camp and went in.
There was to be no miraculous recovery, though, as the Rams endured a frustrating final 30 minutes, which saw assistant manager Johnny Metgod sent to the stands.
And Forest put the icing on the cake in injury time when Earnshaw thumped home from 12 yards, ensuring they remain unbeaten at the City Ground for an impressive 30 games, while the Rams can enjoy no such luxuries either home or away as they suffered their fifth successive defeat.
