The sound comes from Dim Bulb of the Yukon, a Donald Duck cartoon released in 1946, in which Donald plays a dim-witted Mountie in the Yukon. In the short, his exaggerated sniffing is part of the slapstick humour that defined Disney cartoons of the era, with vocal effects pushed far beyond realism for comic effect. Lifted from the film as a standalone clip, it has since circulated among soundboard users who want an instantly recognisable cartoon sniff for reaction videos, edits, and playful detective parodies.
