But perhaps most strikingly of all was the large contingent of new SNP MPs, many of whom dutifully filed into the Commons chamber on Wednesday to witness their very first PMQs from the vantage point of those famous green benches.
A large number were left more than unimpressed though, and wasted no time in telling their tens of thousands of Twitter followers exactly what they thought of the big event.
Some branded the proceedings as "infantile" while others rubbished David Cameron for being "a bully".
First PMQ. Cameron behaves like a public school bully. And he shouts. You'd think by now he'd have some gravitas. Sadly not. Needs changing.— Tommy Sheppard (@TommySheppard) June 3, 2015
I'm sitting in the Commons thinking of an adjective to suitably describe my first experience of PMQs. The most appropriate is #shambles— Dr Paul Monaghan MP (@_PaulMonaghan) June 3, 2015ADVERTISEMENT
Sitting in HOC chamber and can't hear any of the speakers Bec folk are talking over them. Why come in if you're not interested? #manners— Anne McLaughlin (@AnneMcLaughlin) June 3, 2015
Patrick Grady's question at PMQs should be coming up soon. After we get past some Tory sycophancy questions.— Natalie McGarry MP (@NatalieMcGarry) June 3, 2015
One newbie, Gavin Newlands, who overturned a more than 15,000 Labour majority in his Paisley and Renfrewshire North constituency, committed the ultimate social media faux-pas, accidentally tagging his commentary with #FMQ (First Minister's Questions - the equivalent of PMQs in the Scottish Parliament).
First observation of #FMQs.
A ridiculous wall of infantile noise cascades down the Tory benches each time a Tory stands or speaks. #boysclub— Gavin Newlands MP (@GavNewlandsSNP) June 3, 2015
But while the latest Scottish additions to the Commons chamber seem scathing in their criticism of PMQs, SNP members are by no means the only MPs with a disdain for the weekly parliamentary proceedings.
Sarah Champion, the re-elected representative for Rotherham, told the BBC on Wednesday she felt PMQs had become "a screaming pantomime".
Labour's Stella Creasy and Ian Austin followed suite and also quickly weighed into the debate:
The House of Commons switches from its worst - #pmqs- to its finest in remembering Charles kennedy and his contribution to Britain ..— stellacreasy (@stellacreasy) June 3, 2015
PMQs doesn't seem to have improved much since March, does it?— Ian Austin (@IanAustinMP) June 3, 2015
Even David Cameron has previously said he finds the whole setup a "nightmare".
But this isn't the first time SNP MPs have clashed with ancient Commons cultures.
Many of the new intake were reprimanded for rallying against Parliamentary procedure, first for clapping in the chamber, then for posting selfies taken in Westminster on their Twitter profiles, and finally for attempting to uproot veteran Labour MP Dennis Skinner from his spot on the 'rebels bench'.
They even managed to cause a stir after Mhairi Black, the 20-year-old who ousted former shadow foreign secretary Douglas Alexander from his Scottish seat, was snapped eating a chip buttie.
We've got the definitive list of ways the new Scottish parliamentarians are defying, what one called, "eighteenth century" traditions.
