A sold out Mattioli Woods Welford Road enjoyed not only a day out in the sunshine but also a bonus-point, 40-7, win for Leicester Tigers, returning Michael Cheika's side to second place on the Gallagher Premiership ladder heading into a European break.
Leicester's outside backs were in scoring form with Adam Radwan registering a hat-trick, while Ollie Hassell-Collins got across for a double in the 33-point victory in front of more than 25,000 fans.
Despite both sides coming with clear plan to test their hand in attack early on, in favourable conditions, it took 16 minutes for the first points of the match.
Thankfully the opening score was worth the wait.
Some slick, quick hands to the right from the home side ended up finding Adam Radwan down the right wing and the finisher did just that, with an impressive, acrobatic dive for the corner much to the delight of the Terrace.
Shortly after and Radwan's back three teammate, Freddie Steward, was taken in the air while attempting to defuse a Harlequins bomb, which saw Cameron Anderson shown a yellow card and meant the visitors were down to 14 men for the next 10 minutes.
Handré Pollard's conversion attempt went wide which meant it would remain 5-0.
On the half-hour mark, the home crowd were up on their feet once again - and not just those standing on the Terrace - when Ollie Hassell-Collins crossed in the North East corner.
After a break down the left touchline from Jack van Poortvliet put Tigers on the front foot, just a few phases later the ball went wide to OHC's wing - including an impressive tap on from Julián Montoya - and the speedster stepped and swerved his way over to make it 10-0.
Pollard was on point with the touchline attempt to extend it to 12-0, where it would remain until the break.
Tommy Reffell was replaced by Emeka Ilione towards the end of the first half after being called in for a Head Injury Assessment (HIA) and passed which saw him return to the field with his teammates from the changing rooms.
Shortly after the break, Anderson was shown a red card after colliding with Steward in the air once again. The collision knocked the Harlequins wing out and he required medical assistance from the field. Play restarted shortly after with Harlequins down a man for the remaining 36 minutes.
The visitors went down to 13 men just two minutes later when Tyrone Green received a yellow card for an intentional knockdown and, just a few phases after Radwan had a second which Pollard converted to make it 19-0.
Radwan had a hat-trick only minutes later, after the TMO awarded the Tigers wing the try, which Pollard converted to make it 26-0. But, as Harlequins made their way back to halfway for the restart, the TMO intervened again with a new angle and the try was rubbed out, meaning the scoreline returned to 19-0.
Thankfully, it didn't take long to get back over the chalk, with fellow wing Hassell-Collins stealing the bonus-point score from him - and getting his second - in the 55th minute. Pollard was on target from out wide to make it 26-0 (again).
Radwan wouldn't be denied a hat-trick just before the hour mark when he hot-stepped his way through for his second third try of the match, much to delight of the home crowd, and Pollard again had the Tigers faithful cheering with another impressive touchline effort to make it 33-7.
After coming on as a replacement, Dan Kelly looked to have scored a sixth for Tigers but was held up in a last ditch effort by Harlequins over the line. But, only minutes later the home side had their sixth when Hanro Liebenberg crashed over from close range.
Jamie Shillcock, on in place of Pollard, landed the conversion to make it 40-7, where it stayed until the final whistle.
