That’s one way to tie the knot!

During Carrie Brownstein‘s reading of her new book Hunger Makes Me a Modern Girl in Pasadena, California, on Tuesday, two fans requested that the author officiate their wedding – and to top it all off, Amy Poehler was on hand to help her pal with the proceedings.

Brownstein, 41, then brought Kendall Oshiro and Genevieve Hernandez on stage.

Poehler, 44, got in on the fun, grabbing some flowers and handing them to the couple before racing to the piano. Entertainment Weekly reports that the actress played “Greensleeves,” according to a Brownstein rep.

Brownstein, a licensed wedding officiant, then officiated the ceremony with an impromptu speech: “In the way that we always root for ourselves, in the way that we root for love to always win out over despair, for hope to win out over fear, all of us here are rooting for you. With the power vested in me by the state of California, I now pronounce you married.”

Portlandia star Brownstein’s intimate new memoir tells the story of her rock band Sleater-Kinney.

“The themes I wanted to explore were able to be contained within Sleater-Kinney. The nature of the band, the story of the band was a better shape for the themes of feeling like an outsider,” Brownstein recently told PEOPLE. “The band felt like it was behind me enough that I was able to write about it. A lot of people think of memoirs as something you write in your 50s and 60s. The story I wanted to tell had already happened, and did feel enough in the past that I was able to bring to it a perspective and an objectivity as much as I could, even though that memoir is subjective.”
