Mariah Carey had a fun time during the holiday-themed episode of Billy on the Street.
The six-minute video, which dropped Monday on YouTube, finds Mariah and host Billy Eichner asking regular New Yorkers to sing holiday songs with them for prizes like menorahs and mini-Christmas trees decorated with copies of Mariah's Glitter CD.
Along the way, Mariah reveals she knows how to speak Swedish (huh?!) and saves the holidays when Eichner accidentally breaks an artificial tree in two and she suggests turning the bottom half into a Hanukkah bush. Eichner agrees and declares, "Jews, thank me later!"
