Put a bunch of hormone-filled 13-year-old Jewish boys in a room and give them one wish and it would probably be having Nicki Minaj show up at a bar mitzvah ... and this weekend, that wish was granted. 13-year-old Matt Murstein's millionaire financier dad called in a few favors, and dropped a few shekels to get the "Anaconda" rapper to help the kid usher in adulthood Saturday night at the Pierre Hotel in NYC. Nicki reportedly performed 7 songs and stuck around for a meet and greet where the boy, sorry ...the MAN made a pass at her! Matt's pickup line obviously didn't work on Nicki, but you gotta appreciate the guy's chutzpah.??
