Query: A Sad Swan Song

The last Abbott and Costello picture together is a sad, unfunny vehicle that is difficult to watch. When this film was made the team was off the screen for over one year and this outing was supposed to be their comeback film. Next to Abbott and Costello Meet the Keystone Cops, this is the team's worst film and finds its way into film collections solely because it is the team's last film together.
