celebrated breaking the 100-goal barrier for Manchester United as they romped to a 5-0 victory at Wigan.
The England striker scored twice at the DW Stadium in a fine second-half show by the champions.
Dimitar Berbatov, Michael Owen - with his first goal for the club - and Nani also found the target as they bounced back from defeat by Burnley.
Antonio Valencia was subjected to abuse from the fans who adored him until his summer switch but was smiling when he supplied the cross that led to the opening goal.
It came from Rooney - a fine header into the corner - and he savoured the moment, the goal his reward for another typically hard shift.
That was the cue for United to turn the screw and Berbatov added a second two minutes later.
He started and finished the move cheekily chipping the ball over Chris Kirkland before finding the net with his second touch after Scholes supplied the through ball.
United made it 3-0 in the 65th minute thanks to Rooney's second goal of the game. There was touch of luck about this effort as his shot took a slight deflection off Mario Melchiot to wrong-foot Kirkland after Berbatov had supplied the opening.
It was damage limitation now for Wigan, who had lost at home to Wolves in midweek. However Owen made it 4-0 to United with his first goal for the club, a cool finish into the corner in the 85th minute after he had been set up by Nani.
And Nani had the final word himself with a superb free-kick in stoppage time from 25 yards that sailed over a stranded Kirkland's head.
