Judd Apatow had quite the experience working with Roseanne Barr and Tom Arnold back in the day. Apatow, 57, recalled being a part of the three-part 1991 HBO special Tom Arnold: The Naked Truth in his new book, Comedy Nerd. That gig led to Apatow writing jokes for both Arnold and Barr. "I was there during the period when she got in trouble for grabbing her crotch and singing the National Anthem. At one point, I decided to ask for a raise," Apatow recalled.
