Morgan takes over the dispensing of facts this episode. Matt takes a back seat and doesn't make enough jokes because switching roles is difficult. As for the film, it's pretty alright. It earns the second spot in our "Elvis as racecar driver" thematic trilogy ranking.
There's another Roger Ebert review to read. He's kinder this time around but still gets in some zingers. Also it can't be stressed enough how this movie's centerpiece is an elaborate musical sequence set in the offices of the IRS.
