Plot
While undergoing a physical exam at his doctor's office, Dennis (Glenn Howerton) is surprised to learn he has high blood pressure. He rejects the doctor's recommendation of medication, insisting that he can command his body to lower his blood pressure and will take care of the problem on his own.

After a video call from the Gang raises his heart rate and blood pressure, Dennis decides to call a mental health day, during which he will go to the beach apart from the Gang. With his car in the shop, Dennis reserves a rental and ends up with a luxury electric vehicle started from an app on his phone, a feature he dislikes intensely. Stopping at a tea shop, Dennis is further aggravated at having to download another app to purchase his drink. After returning to his car, Dennis accidentally leaves his phone on the roof and drives away. Later on, while distracted by the car's warning about a missing 'key', Dennis runs a stop sign and is stopped by a police officer who forces him to exit the car, locking him out.

Dennis decides to buy a new phone, but learns that he can only get one immediately if he adds a new line to his family plan - which is under Frank's (Danny DeVito) name. Back at the bar, the Gang is attempting to make diamonds by adding charcoal to a pressure cooker. Dennis calls Frank to get the PIN for the family plan, but the Gang ignore the call noting Dennis' earlier call for a mental health day. He successfully guesses Frank's PIN and gets a new phone, only to find that the app will not connect to his car. After spending hours on the phone with the rental company and the car maker Dennis engages in an angry diatribe rehashing the futility of his struggle to a customer service representative, finally deciding to register his complains with the CEO of the car company. Upon learning that the CEO is away at his beach house, Dennis confronts him before silently reaching into the man's chest and removing his heart. Tightening his fist around the glowing heart, Dennis forms a diamond, which he then consumes.

The scene then transitions to the clinic, revealing that the events were all a daydream. The doctor is astounded to see that Dennis' blood pressure has lowered 20 points in less than a minute, and Dennis tells him that he just "let off a little steam." Answering a call from Charlie (Charlie Day) about the pressure cooker, and Dennis decides to join their scheme. A relaxed Dennis leaves the office, walking past several people in the clinic who were characters in his fantasy.

Critical reviews
"Dennis Takes a Mental Health Day" received positive reviews from critics. Ray Flook of Bleeding Cool wrote, "Wow! I actually didn't see that whole 'Keyser Söze' thing coming and that we would be taken all the way back to Dennis' initial doctor's visit. That might be one of the best insights into how Dennis' mind works since 'Making Dennis Reynolds a Murderer' and a highly creative note to end the season on."

Jerrica Tisdale of Telltale TV gave the episode a 4 star rating out of 5 rating and wrote, "'Dennis Takes a Mental Health Day' is a brilliant character study that also demonstrates just how annoying everyday life is." Danielle Ryan of /Film wrote, "The characters and situations on It's Always Sunny in Philadelphia may seem too ridiculous to ever be real, but it turns out that sometimes truth and fiction aren't all that different." Jamie Parker of Comic Book Resources praised the episode's themes, saying "'Dennis Takes A Mental Health Day' not only shines a light on the rising need for mental health days and work life balance, but also the dangers of technology. Dennis takes on cars, coffee shops, and tech corporations in his fight for mental relaxation and rejuvenation."
