It was a “chance” ride that left some Chicagoans stunned.

New video released by Lyft Monday showed footage of Chance the Rapper going undercover as a driver in the city, much to the surprise of the unsuspecting riders he picked up.

The “Undercover Lyft” episode shows Chance picking up riders and talking to them about music and the importance of giving back, all while dropping subtle hints at his real identity.

“When we saw the first cut of the footage it was funnier and more real than anything we had expected,” David Katcher, Lyft’s Midwest general manager, said in a statement.

Chance, who told riders his name was John, even offered up a few rhymes for one rider -- but not the kind you’d expect from a music icon.

“I was just like this guy thinks he knows how to rap because I was being very nice,” said rider Imani Abernathy. “I was like, ‘Oh, you know, yeah…keep going. Maybe stick to your day job.’”

The experience was intended to promote a partnership between the rideshare company and the rapper’s non-profit SocialWorks. Under a new program, Lyft riders can round up their fares and donate the difference to a cause of their choice, including SocialWorks’ “New Chance” campaign to benefit CPS.

“I hope this video encourages even more folks to give back just by taking a Lyft,” Chance the Rapper said in a statement.

“It makes me want to be able to donate as much as he does and give back,” Abernathy said. “He’s not forgetting where he’s from.”
