A daring Foo Fighters fan unexpectedly became part of the spectacle at the band’s Sydney stadium concert after accepting an outrageous Mentos challenge from frontman Dave Grohl during Tuesday night’s show, as reported by Page Six.

The moment unfolded during the rock band’s acoustic set as Grohl recalled the history of the “Big Me” music video. Filmed in Sydney in 1996, the video parodied a famous commercial by the candy brand.

@Ambien_ After reading this all I can see in my head is a new commercial with the foo fighters barging into a doctor's office and snatching away an AIDS patient's meds and handing them mentos. https://t.co/WI82CAq6Ye

“I didn’t eat those candies, because after we made this video, people threw those f–king things in my face every night every time we played this song,” Grohl told the crowd of 60,000 fans.

Grohl then noticed a fan named Thomas holding up a packet of the mints from the front rows near the security barrier. The singer immediately made it clear that he did not want Thomas throwing them toward the stage.

“Don’t you f–king dare. I’m telling you, don’t be that guy!” Grohl yelled while pointing at Thomas, who had suddenly attracted the attention of the frontman and the enormous stadium audience.

Instead of risking another airborne Mentos encounter, Grohl offered Thomas a challenge. The fan would have to consume the entire packet while the Foo Fighters performed “Big Me,” with a beer alongside Grohl promised as the prize.

“How about this? I’m going to play this song, and I want to watch you eat that whole f–king pack of Mentos while I’m playing this goddamn song. Keep the camera on this motherf–ker! If you can finish that whole pack before we’re done playing this song … I’ll chug a beer with you.”

Thomas accepted without hesitation. He emptied the entire cylinder of mints into his mouth, then appeared on the stadium’s large screens as he spent the next couple of minutes chewing the candy during the performance.

After completing the challenge, Thomas received a beer passed to him from the stage. Grohl then invited him into the pit directly in front of the stage, transforming the unusual candy stunt into an increasingly memorable concert experience.

The rewards did not stop there. Grohl brought Thomas onto the stage during a later song and invited him backstage to meet the band after the concert, giving the fan a far bigger prize than the promised drink.

Grohl also recognized that combining an entire packet of Mentos with beer could produce an unpleasant result. Mentos dropped into a carbonated beverage can cause an explosive eruption of foam, a reaction that inspired his next round of jokes.

“You know who’s gonna go throw up in my f–king dressing room right now,” Grohl told the crowd. “I’m gonna go back to my dressing room and find Thomas in a pile of puke.

“He just f–king ate a whole pack of Mentos and then chugged a f–king Coors Light.

“It’s like, wait, hold on, isn’t that that thing if you put those in a Pepsi? Ladies and gentlemen, I’m not even kidding. This might be the funnest show we’ve ever played in this f–king city. For real.”

The mood shifted two songs later when Grohl delivered an emotional tribute to Beaconsfield mine collapse survivor Todd Russell. Russell died on Monday following a battle with leukemia.

Russell and Brant Webb were trapped underground for almost two weeks after the Tasmanian mine collapse in 2006. They requested an iPod loaded with Foo Fighters songs to cover the drilling noise while rescuers worked to reach them.

Grohl sent the miners a supportive message and promised them free tickets to any Foo Fighters show. Before a 2006 performance at the Sydney Opera House, he wrote the “Ballad of the Beaconsfield Miners” in his hotel room.

Grohl fulfilled his promise to include the song on the band’s next record, the 2007 album “Echoes, Silences, Patience & Grace.” At the Sydney concert, he dedicated the song to Russell while reflecting on the miner’s impact.

“We lost one of the Beaconsfield miners today … I’ve met a few heroes in my life, but that was a big one, so I’m doing this one tonight for Todd Russell,” Grohl said.

The concert was also interrupted several times as medical and security staff evacuated fans from the packed area in front of the stage. One person left the mosh pit in a wheelchair, while another was removed on a stretcher.

The band monitored the situation from the stage and played “Stairway to Heaven” while the fans received treatment. Following the eventful Sydney performance, the Foo Fighters continue their Take Cover tour this week.

Thanks for having us, Sydney!!!
