Force India driver Sergio Perez brought laughter to the room as he and fellow drivers met for the F1 drivers' briefing ahead of the US GP.
Following a tense meeting in Japan - which saw Lewis Hamilton and Sebastian Vettel clash - all 20 drivers sat in front of FIA race director Charlie Whiting to voice their issues following Friday's practice sessions in Austin.
Esteban Ocon took issue with standing water on the track, while Max Verstappen questioned why the painted white lines were slippy on the Austin track.
The most notable moment of the press conference, though, came almost immediately after it began, when Felipe Massa questioned Sergio Perez's apparent block on Lance Stroll in Q1 two weeks previously.
Massa pitched to Whiting about the disruption in qualifying: "The car that was disturbed couldn't go to Q2... I think to be honest if you block somebody you need to get a penalty. That's normally how it works."
"Do you think you were blocked?" Whiting responded.
"No - I think Sergio blocked Lance [Stroll]," Massa added.
It was at this point that Perez chimed in, seemingly aggrieved but unnerved by Massa's suggestion he faces some form of punishment.
"What are you, his [Stroll's] father?" Perez joked.
"If you cannot pass to Q2 because you are blocked, that is pretty clear, no?" said Massa - see the video below.
Whiting suggested the situation was adequately dealt with by the race stewards who looked into the incident at the time, and Perez agreed.
"I was in the queue. I think it's important that more or less other drivers respect each other and know if you're in the queue then you don't go more or less last minute and overtake someone. It's just what he did but he was coming into the pit."
In the subsequent race on Sunday, Perez and Massa renewed their rivalry by finishing eighth and ninth respectively.
