Sometimes, it would be really great to get a doctor or other medical authority to say something nice about your product and or service on TV. However, for some reason — FDA approval, budget, truth-in-advertising laws prohibiting advertisers from passing non-doctors off as doctors, etc. — it will not be possible to actually get a real doctor to do this.
The solution: dress an actor up in a white lab coat, and give them a stethoscope. Even if he is a dentist. If possible, put them in a set that looks like a waiting room, pharmacy, or hospital. As long as you don't say they're really a doctor, you aren't going to get in trouble, and you still get the subliminal boost in believability that comes from associating the trappings of real medicine with your product.
Trope named for a commercial from the 1980s in which Chris Robinson, who played a physician on General Hospital opened his pitch for Vicks Formula 44 cough syrup with this very line, which became a pre-Internet Memetic Mutation. (How does playing a doctor on TV give someone any authority to prescribe actual medicine?)

At first, a female doctor is introduced, saying that as a doctor, a healthy diet is important to her - then the camera in one fluent motion moves to a second, similar woman (although with different hair color) who will continue where the other woman left off in mid-sentence and happily endorse a specific product. Probably because a doctor may not be allowed to endorse a product directly on tv.
- Played with in a Venezuelan commercial for a headache/flu medication, where two animated mosquitoes say that the medicine in question can't work in dengue patients and the two models dressed as doctors are not of trust because they "only play as doctors on TV".

- An episode of The Puzzle Place in which the characters spend all day watching TV featured a commercial for the "Global Express" credit card in which a puppeteer opens with "Hi.

- An odd variation on All My Children, when Isabella Santos is displeased to find her son-in-law Edmund chatting with a pretty waitress.

- Reshma Shetty was out shopping when someone nearby collapsed. She immediately went into "work mode" and started telling people to call 911, helping the guy out, getting his history, etc. She was able to give a very good medical history to the EMTs who arrived and had to explain to everyone she wasn't a doctor but played a physician's assistant on TV.
- Similarly, when an extra collapsed from heatstroke while filming a scene on ER, actor Noah Wyle rapidly inserted an IV so that she could receive fluids, having clearly learned to do so after years of playing a physician.
- A more serious example shortly after the show began filming. The cast was having lunch at a restaurant, still in their "doctor" outfits, when a child began choking. Everyone promptly looked at all of them, expecting them to help, having clearly mistaken them for real physicians, given their clothing (the show hadn't even aired yet, so no one could recognize them as actors). Luckily, someone else helped the kid, who was fine.

He explained that he'd learned the terminology in his years on M*A*S*H.
