The unintentional joke is when they are in the trash compactor scene and Dr. Tart starts doing something to *help* them get out I laugh really hard from this because it was like why is he doing that before realizing the actual purpose but that is funny before the realization. The movie commences dull and like the scenes having no music just the two playing off each other but if the movie reaches halfway it actually becomes better as in stuff is happening in a turnabout way and some of the jokes do work that the rest of the hokeyness is actual in a relaxing way. Inspector Winship is by the known Knotts and here he is refreshingly more "what the heck are you doing?" to the even dumber characters he's around with, than his other known movies. His blowing his top at his unwilling/dumber sidekick is hilarious at spots.
