“Do you own a doghouse?”

“Do you own a doghouse?”

Impossible stairs

Norm Macdonald in Norm Macdonald: Norm tells a story in which a professor uses doghouse ownership as the starting point for increasingly personal inferences. The narrator then repeats a crude inference to someone else, treating absence of a doghouse as evidence of a conclusion that does not follow. The selected Norm clip's fan archive identifies a neighbor followed by a stranger at a bus stop; a circulating train version differs and is not being used. Do not picture unsupported literal staging. The user approved this exact short question, not the full punchline. A small red-roofed doghouse below an exaggerated rising stair and cream lettering on blue.
