It can be difficult enough for most referees to deal with one zealous fly-half offering tips on how to do their job, but Jaco Peyper will have two to contend with in the 2022 Six Nations opener.
Dan Biggar will captain Wales at this year's tournament in the absence of venerable skipper Alun Wyn Jones, and his first task will be guiding the titleholders past a tough-looking test in Dublin on February 5.
There, they'll encounter an in-form Ireland team led by Biggar's former British and Irish Lions team-mate Johnny Sexton, who also carries a reputation for buzzing around the official's ear.
Rugby captains are expected to act as the conduit between the referee and any playing staff, but fly-half skippers in particular have a renown for pestering officials.
It's the stuff of nightmares if you're the one calling the match, which just so happened to be Biggar's prognosis when predicting how Jaco Peyper must feel in the build-up to the Aviva Stadium curtain-raiser.
The South African will take charge of the opening Six Nations fixture amid a weight of expectation, and it's not only the 30 players on the pitch who will feel that burden of pressure.
"I saw an article Johnny Sexton did," Wales star Biggar told the Rugby Union Weekly podcast. "For the first game Jaco Peyper has got me and him so I bet he's having sleepless nights!
"[In all seriousness] it will be a challenge because my nature is very fiery and competitive. It is kind of a double-edged sword. For me, as a player, I need to be at a level where I am emotionally on edge but obviously there has to be a line.
"I'm really looking forward to testing myself. Only time will tell if it will come across right but I'm going to fly into it the best I can."
Wales had lost four consecutive encounters with Ireland prior to beating them in Cardiff last year en route to the Six Nations crown.
However, Biggar & Co. haven't won in Dublin since August 2015 when they were warming up for that year's Rugby World Cup.
Furthermore, next month's clash falls 10 years to the day after Wales last beat Ireland on their own soil in the Six Nations (February 5, 2012).
Leinster marvel Sexton—who has faced Biggar many times and toured together for the 2017 Lions series in New Zealand—has backed his Welsh counterpart for success: “I text him the other night and said, ‘Congrats.’
"I’m not sure the refs are going to be too happy having to deal with me and him! But there will be two of us in it anyway.
“He’s a good choice, he’s a leader and obviously one of the first names on the team sheet. He’s a Test match player. He’ll be good for them I think.”
Peyper will referee only two fixtures during this Six Nations, but each involvement as the first official promises to have huge bearing on who claims the crown.
He'll take charge of the tournament-opener in Dublin before officiating the final match of the competition when England meet France in Paris, which has the makings of a championship-decider between the two favourites.
Only the former will concern Northampton Saints star Biggar, however, as he looks to fill some sizeable boots by replicating Jones' success in the role and taking Wayne Pivac's side to successive Six Nations titles.
