From his later years must be mentioned an almost silent sketch in which he portrays a man's vain attempt to stop smoking (also shown in West German TV).

A Danish critic, Jens Kistrup, once said that one of the secrets behind the comedy of Passer was its combination of elements that are normally regarded as incompatible.

He possessed noisiness and discretion, loudness and quietness, boundlessness and complete control, craziness and softness – all this combined with a special intimacy with the audience.
