[None] of [What's Up, Tiger Lily?] is precisely what used to be called boffo humor. No custard pies fill the air, and the climax contains no lunatic chase in break-away cars.

Allen's humor is without malice and without effort; and if some of his puns are terrible, there is an added fillip of fun in the realization that he is every bit as aware of it as we are.
