In ALF's most offbeat episode, the obstreperous little alien subs for Johnny Carson as host of The Tonight Show. It doesn't take long for ALF to alienate Johnny's announcer Ed McMahon and Tommy Newsom, but the "fun" really begins when he matches wits with guests Joan Embery, Dr. Joyce Brothers and Rich Little. All these shenanigans serve as clever method to present a "clip" show comprised of highlights from past ALF episodes. Originally telecast as a one-hour special, "Tonight, Tonight" has since been edited into two half-hours for syndication.
