Matt Harrold fired a hat-trick as he helped Brentford ease into the FA Cup second round with a 7-1 win against Gainsborough at Griffin Park.
Harrold a sparked a goal rush with his first for Brentford on the stroke of half-time, before adding two more on 65 and 86 minutes.
It was rough justice for the Unibond Premier League part-timers, who had their Division Two opponents on the ropes for much of the first half.
But after Harrold's opener it was all one way traffic, and Tony Rougier made it two a minute after the restart.
It was followed four minutes later by Chris Timons' own goal after Stephen Hunt's cross whistled past Harrold's head.
Andy Frampton was next to get on the scoresheet when he volleyed in the rebound after Eddie Hutchinson's effort came back to him off the crossbar. And Kevin O'Connor made it six with 14 minutes left on the clock with a thundering free-kick.
Lee Ellington struck a consolation for the visitors on 82 minutes after Brentford failed to clear a corner.
But Harrold was on hand at the other end to complete the rout for Brentford with a powerful header past keeper Paul Norton.
Striker Gareth Grant should have put Gainsborough ahead on 20 minutes when he was left one on one with keeper Paul Smith, but fired wide of the far post.
Gainsborough boss Paul Mitchell said: "I am shell-shocked by the result. I have never lost 7-1, but if you're going to, you may as well lose playing as well as we did.
"I am pleased with the way we kept the ball and played some football. We can feel proud of our efforts.
"It is frustrating to have played so well in the first half then let them in with some mistakes.But I can't believe we were beaten by that scoreline." Brentford manager Wally Downes said: "I am pleased we are through, but they didn't deserve that sort of scoreline. I am glad they scored.
"They didn't deserve to be beaten by as much as they did.
"I was worried in the first half, because it was classic FA Cup upset material.
"I am pleased with the speed Matt Harrold has come on. He has the potential to be a good player.
"It was his first FA Cup game and he will remember it forever. But we have to make sure we don't rush him. He's given me a nice selection headache for Tuesday night's game against QPR."
