Wayne Rooney scored all four goals in Manchester United's 4-0 defeat of Hull City, to put them back at the top of the Premier League.
The star striker netted his first early on, from a rebound after a Paul Scholes shot was denied.
A hat-trick in the last 10 minutes of the match gave United an undisputed home win and boosts Rooney's goal tally so far this season to 20.
The match also saw the return of Rio Ferdinand after three months off.
It was the weekend's only Premier League fixture due to other clubs' involvement in the FA Cup.
