The recordings — peppered with dad jokes (“The next stop is Manhattan so we’re going underwater, hold your breath!”) and fun facts about New York (“This is 42nd Street-Bryant Park, the New York City Public Library is here!”) — are the first in a pilot program by the Metropolitan Transportation Authority and its advertising partner, Outfront Media, to tap celebrity announcers.

Awkwafina will be the voice of the 7 train for the next week.

“We are exploring new and different ways to generate much needed revenue, while also surprising and delighting customers,” said Sarah Meyer, chief customer officer at M.T.A. New York City Transit, in a statement. “Our focus will always be to run the trains safely and on time, and if a well-known voice can bring attention to in-car messaging, we are all for it.”

Transit officials said they had not yet added another celebrity announcer to the list and are soliciting feedback from riders about the Awkwafina No. 7 train takeover to determine if they will do so. They did not say how much Comedy Central had paid for the campaign.
