Fernando Alonso is off to try winning the this weekend, so mostly-retired McLaren teammate is standing in for him at the Formula One Monaco Grand Prix. McLaren got Alonso on the team radio to give Button some words of good luck. In return, Button said he’ll pee in the seat.

Alonso deeply wants to win the Triple Crown of Motorsport: Monaco, Indy and Le Mans. Alonso has already won the Monaco Grand Prix in the past, and this year’s McLaren is a dog that had to start from pit lane due to a preventative , so he’s trying to tick off a second race in the Triple Crown instead: Indianapolis.

So, McLaren let Alonso give Button some words of encouragement on the radio to his stand-in and friend ahead of the Monaco Grand Prix, piping in a phone call from Indianapolis through to Button’s in-car radio:

Jenson, my friend. I’m sure you wanted to hear my voice before starting the race. We are wishing you the best of luck. We’re following you here on television. You did amazing yesterday, so yeah, please...take care of my car.

Button’s response to this sweet gesture was classic:

Aww, thank you! Okay. I’m going to pee in your seat.

Hey, man. He’s just keeping it warm!

Alonso, of course, got the joke and responded with:

No, please. Have fun! You did amazing yesterday. Amazing job. Congratulations.

Button qualified ninth before grid penalties moved him to the back for today’s race, at which point McLaren opted to start him from pit lane. Button pitted almost immediately at the start of the race, hoping to make up time as other teams bring their cars in to pit later. Sauber’s Pascal Wehrlein was the only other one on the same strategy, nearly making contact with Button in an unsafe release after the two pitted at the same time.

So far, Monaco has been relatively clean, however, with the only major problem being on a Renault for once—not Alonso’s cursed McLaren. Nico Hülkenberg aid down a massive smokescreen thanks to a gearbox problem that forced him to retire, pulling off right before Monaco’s infamous tunnel.
