Brentford moved into the Third Round of the Carling Cup for the first time since 1991 with a 2-1 win over Hull City.
The Championship side took the lead early on but could have no qualms with the result as Robbie Simpson scored a brilliant equaliser and Marcus Bean scored a winner that may have been even better.
The central midfielder's first goal for more than a season was enough to put The Bees into the last 32, where the biggest clubs in the land await.
The Bees started with more than their fair share of possession but it was Hull who had the early chances.
And the visitors took the lead with their first sight of goal when Simpson miss-headed a Richard Garcia cross into the path of Mark Cullen, who finished with aplomb from ten yards.
The Championship side kept coming forward, looking for a key second goal - Richard Lee saved well from a curling Nolberto Solano free kick and then did well to palm away a fierce Robert Koren shot.
But The Bees began to get a grip back on the game, firstly by taking over the midfield and then creating openings of their own.
And by the time the levelled on the 20-minute mark they probably deserved it.
The goal was one of rare quality - Simpson curling a free kick from 25 yards past the despairing dive of Matt Duke and into the corner.
Gary Alexander almost turned the game around completely with a curling effort from the left side that flew inches wide and another Simpson free kick flew into the grateful arms of Duke.
Leon Legge headed wide and Charlie MacDonald had a fierce shot blocked as The Bees ended the half strongly, although Lee also had to be alert at the other end to save a shot from Kevin Kilbane.
Myles Weston had a shot blocked early in the second period but Hull had a lot of the ball just after the re-start and came close to re-taking the lead.
Lee saved from Tom Cairney but he was left helpless by a deflected Koren effort and was thankful to see it bounce to safety off the past.
As with the first period, Brentford gradually took control of a more open second half.
Jamie Devitt shot wide for Hull before Alexander curled a shot which Duke held at full stretch after a nice lay off by MacDonald.
The Bees went even closer midway through the half when Alexander met a Craig Woodman corner with a firm downward header but Duke somehow turned it round the post at full stretch.
Simpson looked set to give The Bees a lead they had by now merited when he latched on to a MacDonald pass but Kilbane got back to make a tackle that looked suspiciously like a foul with the Bees goal scorer set to shoot from ten yards.
The game was flowing from end to end, both sides keen to win it before extra time, but the best chances were still falling to Brentford.
Alexander shot over from 20 yards after good work by Weston and then headed a Kevin O'Connor corner narrowly over.
Hull were mainly restricted to long range efforts - with new signing Jay Simpson withdrawn in the final quarter after being completely dominated by Legge and Karleigh Osborne - but Lee was forced into a fine save high to his right from a curling Cairney free kick.
The Bees hit the woodwork late on when a Weston cross flicked the crossbar with Duke left stranded.
Cullen had the ball in the net for the Championship side with a delightful lob but it was ruled out for offside as The Bees got their trap just about right.
Liam Cooper headed a corner wide for Hull before Simpson smashed a cross-cum-shot all the way along the six-yard box that just eluded MacDonald and Weston.
The goal The Bees had been threatening came with two minutes left and it was a goal that deserved to win any game - Simpson fed MacDonald on the right and he floated a ball in, perfect for the arriving Bean to power a diving header into the bottom corner to win the tie.
But Hull almost saved themselves with a curling Solano free kick that Lee saved and then grabbed at the second attempt.
