The most exciting scenes of the United States Grand Prix from Sunday happened to take place during the podium interviews.
Daniel Ricciardo, who is famous for performing the "shoey", convinced actor Gerard Butler to get in on the act.
The 27-year-old introduced this tradition, which usually involves drinking champagne from his shoe, to the Formula 1 and has done it twice when he made the podium.

The Australian had promised earlier that he would only perform the feat if he won a race, which led to him turning his attentions to the Scottish actor.
Butler was conducting the podium interviews in Austin and seemed to be caught off guard by Ricciardo's strange request. However, the 46-year-old entertainer proved to be rather sporting and accepted the racer's invitation.

Ricciardo provided a polite request to the actor: "Just quickly. I hear Mr Butler does not drink alcohol, I respect that completely but I believe he's going to drink some Red Bull out of my shoe right now. The race wasn't that exciting but hopefully now."
The actor of the movie 300 replied: "Listen I love Red Bull, you've got to be kidding me, I hate you", before reluctantly taking the driver's sweaty shoe.
Gulping down the energy drink in one attempt, Butler commented: "It's actually quite tasty!"
On being asked how it tasted from Ricciardo, the Scottish actor replied: "Well, Red Bull is quite a powerful drink, so fortunately it tastes mostly of Red Bull."

Despite bringing this tradition to the F1, Ricciardo was not the first to try this.
He has admitted to have gained inspiration from a few Aussies as well as Moto GP champion Valentino Rossi for the unique podium celebration.
Even fellow Australian racer Mark Webber was not spared during the Belgian Grand Prix when he was conducting the podium interviews.
Lewis Hamilton, who was next up for the interviews in Austin, seemed too baffled by what he had just witnessed to speak about the race.
The British racer has closed the gap to 26 points at the top of the Driver's Championships after winning the race, beating title rival and Mercedes teammate Nico Rosberg in the process.
