!!Straight Examples

Note that in some of these, the miniatures aren't actually dressed as angels or devils; perhaps to admit that the issues they're debating aren't as serious as good and evil.
* In one of Apple's ads, Mac loans PC his iPhoto book, and PC's good/bad angels appear to argue over whether to rip it in half.
* One anti-marijuana PSA had a kid with his pothead friends appearing on one shoulder, and authority figures on the other. More of each kept popping up, until both shoulders were loaded.
%% * Seen in an ad for [=TruMoo=] chocolate milk, a miniature white-clad milkman promotes that it has "no high fructose corn syrup" and healthy ingredients. A mother asks "What's the bad news?" and the red-clad milkman is forced to admit "I got nothing." "He's got nothing" comments the good milkman, and the bad milkman disappears in a puff of red smoke.
%% ** The trope is severely misused in this instance, the devil is supposed to tempt or encourage bad behaviour, not tell you if food you're about to buy is bad for you.
* [[https://www.youtube.com/watch?v=P03K9TyLEJ4 In an old Wendy's commercial]], CEO Dave Thomas is caught between a Dave in a white suit and tie, and one in a red suit and dark glasses. They weren't full miniature figures, just head-and-shoulders floating nearby.
* In one Dunkin' Donuts commercial, Fred the Baker is about to get up early to start his day, grumbling "Time to make the donuts..." like he always does. Then a devil version of himself appears, urging him to and sleep in for a change. But an angel appears reminding him of his responsibility to the customers. After arguing, the angel wins, and Fred says, "All right, I'm up already!" getting out of bed.
* [[https://www.youtube.com/watch?v=fVaxJxmwTYk This Subway ad from 1998]].

!!Subversions, parodies etc.

* One of the "Not going anywhere for a while?" ads for Snickers subverted this by having a cartoon Republican elephant and Democratic donkey appear over a (live-action) voter's head in the voting booth and argue about who the man should vote for. Their arguments are parodies of the presidential candidates of that year (UsefulNotes/GeorgeWBush and UsefulNotes/AlGore); the elephant repeatedly compares himself to his father, while the donkey makes grand claims about [[MemeticMutation inventing things]].
* Played with in one of the Philadelphia cream cheese ads, in that the protagonist herself is actually an angel and therefore has only a devil appear on her shoulder.
* An ad for Tru Moo chocolate milk had a mom deciding whether or not to buy said milk for her son. A mini-angel milkman appears on her shoulder showcasing the nutritional benefits of the product. Then a mini-devil milkman appears on her shoulder, drinking his mini-gallon of chocolate milk, [[http://www.youtube.com/watch?v=qN5S0fCF5rY agreeing with the former.]]
