Woman Sings Stanley Steemer Jingle in Bunch of Different Styles

New York artist Mia Gentile put together this three-minute video of herself singing the Stanley Steemer jingle in a variety of styles (and outfits). She also made it clear that she isn't contributing to a viral marketing campaign and has no official involvement with the cleaning service, making this video an isolated and bewildering act of brand loyalty. What makes people do this sort of thing, anyway? My theory is that the song's been stuck in her head for years and this was the only way to purge it, but even that's a weird reason to put this much effort into honoring a brand that might not even acknowledge it (beyond a quick tweet).
