“We just feel really, super lucky and we had no idea that the one we did last year would be such a hit,” Braff, 47, tells PEOPLE exclusively from the Los Angeles commercial set. “We certainly had no idea they’d ask us back again, so we’re just super excited and honored because it’s the most people that watch anything in the country.”

In the ad promoting T-Mobile’s home internet plans, Travolta, 68, is seen paying homage to hisGreasedays as the trio sing and dance to a revised version of “Summer Nights,” the hit song he sang as Danny Zuko back in 1978 alongside co-starOlivia Newton John.

Braff and Faison had never met the Academy Award winning actor before getting to the set, but say they’ve long been big fans of his work.

“I had aWelcome Back Kotterlunch box,” Braff says of the former sitcom where Travolta played Vinnie Barbarino.

“Listen, I have a really hard time meeting other actors or peers and stuff like that,” Faison, 48, adds. “I get excited for anyone and everyone, but I will tell you this: If you are in my top five, top 10, I’m going to go crazy. Travolta’s in my top five and I went crazy.”

Faison got so giddy meeting Travolta, that Braff had to remind him to keep his cool.

“We had a talk beforehand,” Braff shares. “I said, ‘Donald, be chill. Don’t start asking questions about the movies until we’ve settled this.’ Ten seconds in, he starts asking questions aboutFace/Off.I’m like, “Bro, we had a discussion.'”

TheFake Doctors, Real Friendspodcast hosts even got dance lessons to prepare for the commercial from theSaturday Night Feverstar.

“We have an amazing choreographer and stand-in dancers that are teaching us, but then John does it and you’re like, ‘Oh, how can I look like that?'” Braff says. “And it’s particularly the moves that we’re doing an homage to inGrease.”

“We’ve never seen John Travolta on-screen,” Faison explains. “We’ve only seen characters that he plays, and it’s very clear when you’re having a conversation with him that he’s nothing like these characters. I’m sure he has some sort of connection to them, so one of the first questions I asked him was about his walk inSaturday Night Feverand how I tried to imitate it all the time because it’s one of the most iconic walks ever.”
