Peterborough missed two penalties, yet still thrashed 10-man Carlisle United.
Tommy Rowe tapped in and Craig Mackail-Smith headed home to see the hosts go comfortably ahead, before George Boyd slotted in a third before half-time.
Grant McCann then had his penalty saved before Carlisle's Liam Cooper was sent off for a second yellow card offence.
Ryan Bennett smashed in a fourth, Boyd volleyed home and David Ball fired in to make it six, but Boyd blew his hat-trick when he too missed a penalty.
Darren Ferguson's free-scoring Posh, who remain just one point off an automatic promotion place, needed just 80 seconds to open the scoring before going on to claim their biggest win in three years.
After Rowe raced into the box to tuck away Mackail-Smith's low cross from point-blank range, League One's top scorer turned from provider to scorer as he doubled Posh's advantage with a high-class header after 24 minutes.
And the points were in the bag when Boyd weaved his way through a couple of tame tackles and nonchalantly prodded the ball under the body of Carlisle keeper Adam Collin in first-half stoppage-time.
Skipper McCann spurned a glorious opportunity for number four when seeing his spot-kick - awarded for a Frank Simek shove on Mackail-Smith - saved by Collin early in the second period.
Carlisle then had on-loan centre-half Cooper dismissed for a second caution just after the hour - and Posh mercilessly took further advantage.
Defender Bennett lashed in on the half-volley after 77 minutes before Boyd added the fifth with a deflected volley eight minutes later.
Substitute David Ball brought up the half-dozen when slamming home after being picked out by fellow replacement Nat Mendez-Laing with a minute remaining. And there was still time for Boyd to miss a second Posh spot-kick.
Peterborough United manager Darren Ferguson:
"It was an excellent afternoon's work. I really enjoyed watching my team play today.
"It should have been double figures and it's no disrespect to Carlisle to say they were lucky.
"I think the promotion race will go down to the wire, but we've got a good siege mentality."
