->''"They mean well, poor souls, and they dress neatly and keep a cheery smile, but they must have been shortchanged in the smarts department because all they care about in this life is how white their whites get."''
-->-- '''Creator/RogerEbert''', review of ''$1,000,000 Duck''

In advertising, customers are routinely shown to be extremely and conspicuously ecstatic about the product, no matter how mundane -- or in fact boring -- it is. This works in all formats: visual forms of advertisement may show people grinning inanely, laughing and jumping for joy, radio spots may have people cheering and going ''woo-hoo'' in the background because they saved pennies on a bubblegum purchase, got a free sandwich with their car or are just generally pleased with the overall product because, [[{{Anvilicious}} you know, it's just so good]].

The trademark stupid grin fits well in the psychological profile of someone who is TooIncompetentToOperateABlanket and in touch with ThePowerOfCheese. When taken UpToEleven, it can give off HappinessIsMandatory vibes or alternatively sexual overtones when the ficticious customers seem really turned on by something that's usually considered unerotic in RealLife, unless you're into [[{{Fetish}} that kind of thing]].

Often happily married to MagicallyDelicious.

''As this is an OmnipresentTrope in advertising, there's no need to list straight examples here. Feel free to list this trope on the pages of works where it occurs.''

!!Examples of parodies, aversions, subversions, instances where this is played with etc.

* In ''WesternAnimation/{{Batman The Animated Series}}'', one of the Joker's schemes involved making a commercial. Even with the Joker's usual level of trademark enthusiasm, the commercial barely seemed out of place.
* Exaggerated in the Enzyte commercials, where Bob (and eventually, everyone else) is a persistent StepfordSmiler, even though the main effects of the product are never shown.
* Parodied in Music/TheAustinLoungeLizards music video ''"The Drugs I Need."''
* In the Music/{{Evanescence}} music video for "Everybody's Fool" Amy Lee's character plays one to emphasize her StepfordSmiler status.
* Paul Kane's short story "Life-O-Matic" takes place in a world where ''everybody'' is like this -- until the protagonist, Jeff, wakes up and realizes how creepy it is.
-->And yes, as June kept telling him, they had dozens of cleaning implements that could reach even into the smallest of nooks or crannies, but Jeff never actually saw her using any of them, only on small sections of the carpet which she would spill wine on deliberately just to show him how easy it was to "foam-away"!
