Jason Segel's nude scene in "Forgetting Sarah Marshall" is already the talk of cyberspace -- and the movie doesn't even open until Friday! Being a family-friendly show that airs in many markets in the morning, Alison had to gently tiptoe around the subject when Jason and uber-producer Judd Apatow dropped by for this week's Top Billing. I still had to edit out part of Jason's explanation because I have a mortgage to pay. Catch more of the interview on this weekend's show, as well as Jeffrey & Alison's review. Now, take a listen to Jason telling Alison how he got ...er, UP, for his big nude scene. Very entertaining.
