from all the don knotts and tim conway film i have see and this be by far my favorite . the brilliant chemistry between the actor be enough to keep the movie go and but it doesn not stop there . the plot itself and while admittedly spoofed and be intrigue and and i do not expect the end at all the first time i saw it . the foul up poem be always good for a laugh and not to mention the exceptionally well play stoff and ( not staff ) . the time gun gag be priceless and and be undoubtedly an idea of conway himself . from what i recall from an interview i saw with don knotts and he say this and and all others with conway be personal favorite and because they be so hard to produce . a he put it and it take probably three or four time as long to film a it should have because he and conway couldn not stop improvise the script and and laughing and and so on . this be one film that i would love to see outtake from . in all and a very good film with load of laugh . some subtle and some in your face and but all around a really good film .
