Darvel pulled off one of the biggest shocks in the history of the Scottish Cup on Monday when they dumped out Premiership side Aberdeen.
Jordan Kirkpatrick's deflected first-half strike was enough to secure a 1-0 win for the sixth tier West of Scotland Football League outfit.
Aberdeen, who sit fifth in the Premiership, pressed on in search of an equaliser, but goalkeeper Chris Truesdale made several fine close-range saves to deny Dons forwards Ryan Duncan and Luis Lopes.
Darvel manager Mick Kennedy said: "I believed in the guys all week. It's about togetherness and love and respect. We've been driving that home all week.
"We probably deserved going in front. We had to show our togetherness. The community has been unbelievable. From the first day I came here I told the board we are going to build something special."
Meanwhile, Aberdeen boss Jim Goodwin is under serious pressure after Monday's result made it seven defeats from their last nine games.
Goodwin said: "I don't want to talk about how bad my team's performance was, I want to congratulate Darvel.
"I thought they were excellent on the night, got their noses in front and defended for their lives. They thoroughly deserved their victory."
The sixth-tier outfit, who will host Falkirk in the last-16, had to come through four rounds to earn a shot at Dons, beating Haddington Athletic, Tynecastle, Dalbeattie Star and Montrose.
Monday's result will undoubtedly go down in history as one of the biggest upsets in 149 years of the Scottish Cup, but there are plenty of other giant-killings that rank highly.
Cast your mind back to the 1999/2000 campaign, John Barnes had come in to replace Jozef Venglos as Celtic manager and the likes of Henrik Larsson, Mark Viduka, Ian Wright and Paul Lambert were wearing the famous green and white hoops.
After finishing runners-up in the 1998/1999 Scottish Cup, Celtic, priced at to win the Scottish Cup this season, were fancied to go one better the following campaign, however, they failed to get out of the third round.
It was a night that has gone down in history, for all of the wrong reasons as far as the Bhoys are concerned, as Inverness Caledonian Thistle ran out 3-1 winners Caley, who are currently to win the Scottish Cup, were a part-time team in the First Division but they showed spirit to win at Celtic, sending their superstars packing.
It emerged after the game that Viduka had refused to return to the field for the second half after a dressing room blow-up with assistant coach Eric Black.
Unsurprisingly, Barnes lost his job just two days later with Celtic a laughing stock, especially after the Scottish Sun ran with the legendary headinline "'Super Caley go ballistic, Celtic are Atrocious!".
St Johnstone were flying high at the end of the 2022/21 campaign after winning the Scottish Cup and Scottish League Cup.
They became just the fourth club to complete that domestic cup double and entered the following campaign with ambition to kick on further.
However, 12 months is a long time in football and the Saints learned how quickly you can go from the highs of Hampden glory to the lows of losing to a League Two outfit.
It's worth noting that St Johnstone's form wasn't great ahead of their fourth-round tie with League Two Kelty Hearts, having lost nine in a row to sit bottom of the top-flight, but they would have been hoping to utilise their trip to Central Park to restore confidence.
However, Kelty, clearly eager to pull off an upset, were up and at their rivals from the outset.
The two clubs couldn't be separated inside 90 minutes but Kallum Higginbotham stepped up for Kelty in extra time to seal a 1-0 win, handing the holders a premature exit.
After relegation from the Premiership in 2019/20, it's fair to say that Hearts' main focus for the following term was securing a route back to the top-flight.
That's certainly the excuse they will use when anyone reminds them of their shocking defeat to fifth tier side Brora Rangers in the Scottish Cup.
Hearts, available at to win the Scottish Cup this term, had finished runners-up in the competition in their previous campaign but they were knocked out in the second round as their focus lay elsewhere.
Jordan MacRae and Martin McLean scored either side of Christophe Berra to seal a 2-1 victory for the Cattachs at Dudgeon Park.
Brora didn't manage to enjoy a fairytale run deep in the competition as they came unstuck against Stranraer in the following round.
