SEE: 'First Class' L Ride Comes With Cider, Towels And $100 Bill

WILLIAMSBURG, BROOKLYN — Just when L train riders thought they couldn't catch a break.

A group of straphangers riding through the Canarsie tunnel suddenly found themselves in perhaps the only "first class subway car" — a train with two suited performers offering butler-style service.

The two men announced to riders that the train was "now a first class subway car" as it left First Avenue. Turning on classical music, they started handing out sparkling cider and warm towels, Korsha Wilson, who was on the train, told Patch.

The performers, who were being filmed but wouldn't say for what, kept the stunt going even after they reached Brooklyn, Wilson said.

"As people got on at Bedford Ave they stopped them and said, 'Excuse me, this is a first class car,'" she said, adding that she didn't take any of the cider or towels.

Those who did indulge in the first-class treatment were given tabs, like those given at a restaurant, at the end of their ride, Wilson said. Inside a check book was a bill that read "First Class Subway Car Experience – $100."

"They then repeatedly asked everyone to pay their tab," Wilson said. "No one did."

The two performers got off at the Lorimer Street station.

In true New York City fashion, some Twitter users replying to Wilson's video of the experience seemed skeptical of the entire experience.

"Meh, I would be hesitant to accept an unidentified drink in a solo cup from two guys that look like they belong to a cult," one Twitter user called Smartacus wrote.

Others, though, were simply curious.

"I want to know so much more. is this performance art? transit activism? a branding exercise on behalf of the champagne company?," Tracie McMillan said.

"Why is Justin Trudeau on the L?" another user chimed in, noting the performer's likeness to the Canadian prime minister.

Some users surmised that improv groups that have pulled similar subway pranks might be behind the stunt.

The group Improv Everywhere, who hosts the annual "No Pants Subway Ride," has done similar things, including the time it turned the 23rd Street station into an art gallery with a cellist, coat check and champagne.
