Scott "Shappy" Shapiro's dad died unexpectedly in January (I believe) while the guys were in California for radio conference. He decided to go back to Phoenix full-time and be with his mother to take care of his parents' business. I believe he is somewhat independently wealthy and did not need the job; that factored in his decision to leave Paul and Old Ron. It's too bad; in the short time he was there he made quite an impact with the show. Having done stand up comedy, he was naturally funny. The cast loved him.
