Well, we’ve come to it: Season 15. The end of the line. Ronnie and Jazz go long with the two-headed premiere of “Under the Skin” and “Awakenings”, which is variously about men’s chests, bad impersonations, lesbianism, unrequited love, face ripping and a terrible Iggy Pop cover. The hosts try to keep their sanity by discussing shows from UPN. Remember The Sentinel?
