Brentford moved in to the Southern Quarter Finals of the Johnstone's Paint Trophy after demolishing Charlton Athletic at The Valley.
Blair Adams scored his first professional goal inside 70 seconds and Brentford just got better and better.
Kevin O'Connor scored from the penalty spot and Toumani Diagouraga, who ran the game from start to finish, added a third in the second half.
Charlton were barely competitive in the first quarter and only a little better thereafter as Brentford deservedly progressed.
Brentford could not have started better, scoring with their first attack.
Diagouraga was at the heart of it, finding space in midfield and picking out David Clarkson with a fine pass, the striker twisted clear and fired low, John Sullivan kept it out but Adams was quickest to react, slotting home.
The home side could have levelled when Matt Taylor was left unmarked at a corner but his header was off target and Gary Doherty couldn't head it back towards goal.
But it was Brentford who were on top - a fine move involving Adam Thompson, Myles Weston and Clarkson set up a shooting chance for Diagouraga but Doherty made a tackle to take pace off the shot and Taylor blocked.
Marcus Bean had a shot deflected wide and Clarkson volleyed over as Brentford threatened to take the game away from their hosts.
Clarkson shot across the face of goal soon after and Adams missed his kick in front of goal after Craig Woodman and Diagouraga had laid on another chance.
Brentford were superior to Charlton in all areas of the game, tactically and technically they were too good for the League One leaders - particularly in the first quarter of the game - as they pressed them in possession and passed around them when they won the ball back.
The Bees' class was emphasised by their second goal - Doherty got no distance on a headed clearance and Diagouraga robbed Mikel Alonso on the edge of the penalty area before he was brought crashing down inside the box as the Charlton man tried to win the ball back.
Referee James Linington had a simple decision to award the penalty and O'Connor smashed it past Sullivan to give the visitors a lead that was the least they deserved.
Sullivan had to save at the feet of Clarkson to stop the striker making it three before Simon Moore was called in to action for the first time, getting down well to keep out a powerful Danny Green free kick.
But that was a chance against the run of play for the home side - Weston should have made it three with a diving header from a Thompson cross and such was Brentford's dominance that Charlton switched to 4-3-3 to match up and try and get a foot hold in the game.
Paul Hayes missed the target with a long range volley and Alonso sliced an effort horribly wide but Brentford went to the break with their 2-0 lead in tact.
The home side had improved with their switch in formation and improved further at the start of the second half, following a double substitution.
But they were still second best and Brentford created all the chances in the opening stages of the second period.
Diagouraga had a looping header saved before Adams fired wide from 20 yards after a run from deep.
Sullivan saved a Bean volley soon after as The Bees continued to thrive while Charlton wilted under the visitors' pressure.
The game was just about up just past the hour mark when the brilliant Diagouraga added a third, albeit in slightly controversial circumstances.
Weston played the ball in from the right and Clarkson challenged in the box, the ball broke to Diagouraga and he left Michael Morrison on the seat of his pants before slotting home.
Assistant referee Mathew Bounassisi had his flag raised but referee Linington signalled that play should continue and awarded the goal, adjudging the ball had come to Diagouraga off a Charlton player.
Miguel Llera saw a free kick deflect narrowly over with Sullivan motionless and substitute Sam Wood fired in to the side netting as Brentford threatened to make it embarrassing.
The closest Charlton came to a riposte was when Marcel Eger, who was superb throughout, diverted a Hayes cross and Moore had to stretch to keep it out.
The Bees almost added a fourth when Woodman ran 60 yards unchallenged before laying the ball wide to Wood, his cross picked out Bean at the far post but his header back across goal flew narrowly wide.
For much of the last half hour Charlton were simply unable to win possession and when they did, they couldn't retain it for long.
Moore had to be alert to keep out a Scott Wagstaff effort but when Green curled the resulting corner straight in to the side netting, it summed up their evening.
Green missed the target with a long range effort late on and Yann Kermorgant lifted an long range effort narrowly over but the game was up by that point.
Weston almost caught out Sullivan with a cross that landed on the roof of the net and Sam Saunders had a shot blocked before Mr Linington brought the evening to a close and Brentford progressed.
