I don’t remember Craig Ferguson, in all these years, ever having a guest host – but tonight, as part of a one-day switcheroo with his former Drew Carey Show co-star and buddy, Ferguson takes tonight off. In his place? Drew Carey, spending time with Carl Reiner, Joan Jett and Cleveland author and journalist Connie Schultz. And since this show airs after midnight, on April Fool’s Day, it’s a same-day trade, because later that same day, Ferguson takes over Carey’s The Price Is Right for a one-day stint. What a deal!
