BANGOR City stole the bragging rights in their Boxing Day derby clash with Caernarfon Town to continue their march back up the table.
Caernarfon were destroyed initially by three goals inside four minutes at the start of the first half, before two more were added within seven minutes of the restart.
Les Davies, Ashley Stott, Martin Beattie and Mike Walsh twice delivered the Bank Holiday delights that enabled the Farrar Road conquerors to extend their successes to 19 games.
Meanwhile, troubled Caernarfon, who are winless in five games and worried, will look to strengthen their under-achieving squad in the new year.
City manager Nev Powell said: “It was a great performance and, because we scored our first goal so early, Caernarfon had to abandon any defensive ideas and come out.
“We were able to capitalise on that situation and had plenty of other chances, so that the score could have been a lot more.
“The players are doing everything with tremendous confidence and are producing some lovely stuff.”
Meanwhile, Caernarfon’s Steve O’Shaughnessy said: “It was totally embarrassing and again we showed that we cannot defend, with that clean sheet still beyond us after 20-plus games.
“We had chances when we attacked and it was that sort of game that could have ended up at 12-6 but Bangor looked sharp, because it is easy to look sharp, when you gain a 3-0 lead so quickly.
“In the new year, when the transfer window opens, I shall be looking to bring in new players to strengthen the squad as a top priority.”
Some of the 700-plus crowd had not clicked through the turnstiles, when Davies celebrated City’s opening goal on five minutes, flicking a tight-angled cross from the right wing.
Stott was also in the six yard box a minute later to bundle the ball over the line after a corner and Bangor’s joy became 3-0 on nine minutes, with Walsh’s close-range finish to a free-kick.
Counter-raids by Town might well have yielded replies but City’s Paul Smith blocked from Tim Ojapah and rushed out of his box to deny John Rowley.
The rest of the first half was a catalogue of Bangor offerings by Davies, Scott, Sion Edwards, Marc Limbert, Walsh and Chris Seargeant but Caernarfon somehow survived more pain.
The second half had gone just 75 seconds, when Bangor’s lead was increased to 4-0 by Beattie’s point-blank strike and Walsh followed up on 53 minutes with a five yard effort from a corner.
Rowley, who was a lone campaigner for Caernarfon without much support, eventually saw sub Bobby Jones succeed, with a firm header on 85 minutes from a free-kick that was of scant consolation as the visitors were well and truly beaten.
