Fulham climbed to eighth in the Barclays Premier League with a three-goal demolition of Middlesbrough at Craven Cottage.
Goals from Jimmy Bullard, Danny Murphy (penalty) and Clint Dempsey ensured the Cottagers stretched their unbeaten run to seven games.
It left Middlesbrough without a win in six matches and continuing to flirt with the edges of the relegation zone.
Fulham started brightly but it was the visitors who enjoyed the first effort on goal.
Chelsea target Tuncay tried his luck from 25 yards with a shot that went straight into the arms of former Middlesbrough stalwart Mark Schwarzer.
A neat run down the right flank by Adam Johnson should have brought Middlesbrough more reward in the 15th minute, but the winger failed to deliver a cross into the penalty area.
Fulham should have taken the lead shortly afterwards, but John Pantsil headed Danny Murphy's corner wide of the target from six yards.
Julio Arca almost put through his own goal in the 21st minute when he cleared the ball off the toes of Simon Davies but fortunately for Middlesbrough it went just wide of the post.
In the 23rd minute, Tuncay was guilty of a glaring miss for Middlesbrough as he sent a free header flashing wide of the far post from 10 yards.
In the 26th minute Murphy found Andrew Johnson inside the Middlesbrough penalty area, but the Fulham striker took too long to make a decision, and the chance was lost.
Fulham's Johnson squandered another chance on the half-hour when Pantsil's ball put him in the clear, but Turnbull reacted fast enough to deny the striker with a fine save.
Fulham lost Zoltan Gera moments later through injury, and he was replaced by Bobby Zamora.
But Middlesbrough were still dangerous, and it needed a double save from Schwarzer to deny both Jeremie Aliadiere and Adam Johnson.
Davies was inches wide with a curling effort in the 34th minute after referee Keith Stroud had waved away penalty appeals for handball against McMahon.
A minute later Arca was lucky not be red-carded for a dreadful over the top lunge on Andrew Johnson.
The Fulham striker was fit enough to continue but words were expressed on the touchline between Fulham coach Roy Hodgson and Middlesbrough's Gareth Southgate.
But Arca's x-rated challenge was forgotten in the 41st minute when Fulham got the breakthrough they deserved.
Pantsil's cross eluded Andrew Johnson but not Zamora on the edge of the six-yard box.
The Fulham substitute's shot on the turn was superbly saved by Turnbull but the fleet-footed Bullard nipped in to the fire the loose ball into the net.
Moments later Stroud felt the wrath of Fulham fans again when he adjudged Zamora to have handled the ball on the edge of the penalty area.
Arca was removed at the interval in favour of striker Mido as Middlesbrough looked to get themselves back into the game.
Tuncay wasted a chance to equalise in the 50th minute when Aliadiere headed the ball back to him inside the penalty area.
However, the Middlesbrough midfielder miscued his shot and it bounced into Schwarzer's hands.
Referee Stroud was at the centre of yet more controversy in the 54th minute when Fulham were awarded a penalty for handball against McMahon.
It was a harsh decision against the defender who could do nothing about the ball rebounding onto his arm after Zamora had blocked his attempted clearance.
Stroud waved away Middlesbrough's protests and Murphy stepped up to score from the spot.
Clint Dempsey almost provided Andrew Johnson with a chance to make it three in the 58th minute but Turnbull rushed out to take the ball off the striker's feet.
But Dempsey made it three a minute later as Fulham tore Middlesbrough apart.
Johnson collected the ball on the left flank and fed the waiting Murphy who in turn sent Dempsey clear with a perfectly weighted pass.
The Fulham midfielder kept his cool to slot the ball beyond the advancing Turnbull and put the home side in a real festive mood.
Turnbull saved superbly to deny the impressive Johnson in the 81st minute after Zamora had put him clear.
Middlesbrough tried in vain to grab some kind of consolation but Fulham were in no mood to provide early Christmas gifts and ran out comfortable winners.
