The line comes from The Pink Panther animated series, specifically the episode titled Sink Pink, where the show's wry narration turns an everyday observation into a joke. As a standalone soundboard clip, the question works without needing the full episode, because the humour is entirely in the comparison it sets up. That self-contained quality has kept it in circulation among creators who want a quick, quotable setup for videos about relationships, behaviour and animals. It remains useful because the joke is simple, instantly understood and easy to place over almost any contrasting footage.
