Richards was speaking about Olivier Giroud's time at Arsenal, saying that perhaps Giroud didn't get credit because he was never going to be in the same category as the club's legendary French striker, Thierry Henry.
Micach began: "When you've got Henry at the club, and then Giroud, it is chalk and cheese, so you can understand why..."
Carragher jumped in with: "It's like you and [Vincent] Kompany."
Ouch. At least Richards - of course - saw the funny side of Carragher's dig, implying that he was a level below Manchester City's Belgian central defender, bursting into his trademark booming laughter.
The pair were on CBS Sports, discussing Giroud because his brilliant bicycle kick gave Chelsea a precious 1-0 win away at Atletico Madrid in the Champions League last 16 first leg.
It's often said that Giroud does not get the credit he deserves - either at Arsenal or Chelsea - despite the overwhelming number of worldies the 34-year-old striker seems to score with unusual regularity.
However few would put Giroud, ability-wise, on a par with Arsenal and France record goalscorer Henry.
Hence Carra's friendly quip that comparing Giroud to Henry was like Richards being held up to his fellow centre-back Kompany.
Both Richards and Kompany actually played together at Manchester City and with some success. However Kompany - who retired last year to become full-time Anderlecht manager - had a longer and more successful career than Richards, who's two years younger than the Belgian but never quite fulfilled his potential as a player.
Still, Richards did play 245 times for Man City and earn a Premier League winners medal in 2011/12 - which is something that eluded Carragher during his legendary Liverpool career.
But Richards chose the path of guffawing laughter rather than firing back at his fellow defender. And for that, we thank him.
