Zoey Deutch's Our Town castmates thought she got laid when she brought donuts for everyone

If you have dreams of stage stardom, think twice before you set foot in a Krispy Kreme.

Zoey Deutch, who recently made her Broadway debut in a production of Thornton Wilder's Our Town, found herself in an embarrassing situation when an opening night gift to her classmates unwittingly tapped into a racy backstage tradition. "

"I got off the train on 50th St., and the first thing I saw in Times Square was the big Krispy Kreme donut store," Deutch told Jimmy Fallon, recalling the play's opening night on The Tonight Show. "I thought, 'Oh that would be a nice thing to get some people some donuts'... So I brought them in, this was a couple months ago, and a few weeks ago I overheard two castmates talking. I overheard one of them say, 'I heard you had a great date last night, where are the donuts? I was like, 'Donuts? Why would you bring donuts?'" Then it hit her.

"That was the moment that I learned about the Broadway tradition that if you bring donuts to the theater it means you got laid the night before," Deutch explained. "Then I realized on my first day of being in the theater, I didn't know anyone, and I basically walked in saying, 'Hi everyone, nice to meet you, happy day one! I had sex last night!'"

Deutch continued to joke, "A lot of it! Eight dozen worth!"

The Disaster Artist and Everybody Wants Some!! actress told Fallon that not all of the Broadway traditions she's discovered have been quite as coarse, nor was the process of discovery nearly as embarassing. "You cannot say the M-A-C-B-E-T-H word, ever," she said, referring to the centuries-old superstition that saying the name of William Shakespeare's Scottish tragedy aloud in a theater brings immediate bad luck to the production being staged there.

She also revealed that when she "walked into the dressing room for the first time in the theater, there were pennies all over. I thought that was such a beautiful tradition, that whoever was in it before had left it as a good luck token."

The daughter of director Howard Deutch (Pretty in Pink) and actress Lea Thompson (Back to the Future), Deutch is showbusiness royalty. But nearly 15 years after her debut as Maya onThe Suite Life on Deck (at only 15 years old), she's set out to test her mettle on stage.

Our Town is as auspicious a maiden voyage as any young actor can take into the unfamiliar waters of live theater. It won the Pulitzer Prize upon its publication in 1938 and has been in a near-constant state of adaptation and re-adaptation since.

Deutch plays Emily Webb, a hopeful young daughter of the titular town of Grover's Corners who meets a tragic end by the third act. She costars alongside Katie Holmes, Ephraim Sykes, Michelle Wilson, and Jim Parsons, who commands the stage as the play's narrator, called the Stage Manager.
