In Seth Rogen's memoir, Yearbook, he reveals how he auditioned for the role of Eminem's sidekick, Cheddar Bob, in the rapper's 2002 movie "8 Mile." According to Rogen, via The Wrap, the casting director told actors they wouldn't be reading with Eminem, instructing them to bring a friend to play his role, Rabbit. Rogen asked his "Freaks and Geeks" co-star Jason Segel to join him — discovering that Segel was also up for the same part.
"We asked our agents if our auditions could be scheduled one right after the other, so that one of us could audition for Cheddar, with the other reading the Rabbit part, and then we'd switch," Rogen wrote. "We had a sleepover at my apartment the night before the auditions so we could rehearse and then carpooled to the audition together."
The audition, however, went off the rails when they began "laughing hysterically" while reciting the "rappery" dialogue. "Auditioning is embarrassing in the best of times," Rogen wrote, "Add the fact that one of my best friends is watching me do it and that we're both reading for rappers from Detroit, which we could not have been less right for."
