Peyton Manning Becomes the Broncos' 'Summer Intern': 'Opportunity of a Lifetime' 

Peyton Manning's career in the NFL isn't over just yet!

The Denver Broncos revealed on Wednesday that they brought back the beloved quarterback in a new role: summer intern.

"Ever since my retirement I've maintained this itch to get back into football and the time has finally come," Peyton, 45, said in a video announcing the Broncos 2021 football schedule Wednesday.

"The Broncos have brought me back and afforded me the opportunity of a lifetime…. A summer internship," Peyton joked.

The video showed the new "intern" launching mail into people's offices, scrubbing footballs, polishing memorabilia, maintaining the grass, calling out football orders and teaching the Broncos mascot, Thunder, the proper form to spin in an office chair.

During his busy day, Peyton received a prank call from his brother and former New York Giants quarterback, Eli Manning.

"Eli, I told you I'm working, don't bother me," he scoffed before hanging up.

Peyton also had few mishaps throughout the day, such as shrinking football jerseys in the dryer, dropping footballs in the pool, and other unprofessional acts.

"I think things are going great so far," the former Broncos quarterback said in the video. "I've been able to apply my real-world experiences and skill set to this internship."

The decorated football player — who played for the Indianapolis Colts for 14 seasons and four seasons with the Broncos before retiring — also noted that despite his lengthy resume, he still had plenty to learn.

"I thought my resume was pretty extensive. I mean, I have between all 32 NFL teams, but I've learned not even a Hall-of-Famer knows everything," he said.
