Jon Hamm is the patron saint of Bonnaroo.
After Hamm captured the hearts of crowds at the Tennessee music festival by leading a sing-along with Zach Galifiniakis, the two actors stopped to grab lunch at Tupelo Honey Cafe.
Waitress Abby Swartz recognized them immediately and resisted fan-girling out, Chattanooga news website Nooga.com reported. Bonnaroo ran from June 11 to June 14.
"Take this wristband and go to Bonnaroo," Hamm told the waitress, offering her his Bonnaroo artist wristband. "This will get you anywhere you need to go." Artist wristbands also provide access backstage.
Swartz couldn't believe it.
"I mostly kept to myself. But there were times when I would just smile and think, 'There are thousands of people here, and I am the only one who is, basically, Jon Hamm's stand-in,'" she told Nooga.com. "Jon Hamm is amazing, and I would love for him to know that he made my life."
Not to be outdone, Galifianakis kept up with the trend and left the waitress a 250% tip.
