Premise
Those Who Can't is a half-hour sitcom set in Denver, Colorado. The show follows three dysfunctional teachers, played by show creators Adam Cayton-Holland, Andrew Orvedahl and Ben Roy of the Denver-based comedy trio The Grawlix. More inept than the kids they teach, they're out to beat the system as they struggle to survive each day on their own terms. Maria Thayer stars as the school librarian with a bubbling passion for life. The show is set in the fictional Smoot High School, named after the Smoot-Hawley Tariff Act.

The show was originally set up for Amazon Studios who paid $50,000 to shoot the pilot. Amazon gave it a script order for 6 more episodes but ultimately did not order it to series. The show was acquired by truTV as their first-ever full-length scripted comedy and was ordered with 10 episodes. The acquisition was part of truTV's comedy-driven “Way More Fun” programming initiative. When the show was first created, Cayton-Holland stated they wrote the character of Abbey Logan (originally played by comedian Nikki Glaser ), the high-school librarian, as the love interest. Orvedahl stated that in the pilot, Abbey "just sort of lived in the library and served only to flirt with Adam’s character.” The character and role was revised for the shows run at truTV and Abbey is stated to have become "one of the gang" with all the characters now on equal footing.

The show holds a TV-MA rating due to language and sexually suggestive humor. Its title is a reference to the George Bernard Shaw proverb "those who can, do; those who can't, teach."

Main

 * Adam Cayton-Holland as Loren Payton. A Spanish teacher who dwells on the fact that he once spent a semester in Spain, Loren is a major hipster who would rather spend his time at brewery openings than in the classroom. Loren is a spoiled and self-absorbed narcissist who grew up with wealthy parents. Adam Cayton-Holland performing stand-up comedy.jpeg
 * Andrew Orvedahl as Andy Fairbell. A gym teacher/JV volleyball coach/health teacher, Fairbell has a good heart but his naïveté and lack of social skills often leaves him on the receiving end of abuse from others as a result. He has been described as a "human golden retriever." Comedian Andrew Orvedahl, Sept 2014.jpg
 * Ben Roy as Billy Shoemaker. Shoemaker is a former high school punk rocker with tattooed arms and massive anger management issues. Separated from his wife, with whom he shares a son, he struggles to reconcile his past as an anti-establishment troublemaker who spent several years touring with his punk band, "Capitalist Emulsification," with his adult life as a history teacher and responsible family man.

 * Maria Thayer as Abbey Logan. The school librarian, who serves as the voice of reason against the other main cast and their schemes but is shown to be just as depraved as the others when pushed. Maria Thayer by Gage Skidmore.jpg
 * Rory Scovel as Principal Geoffrey Quinn.  The naive school principal, who is just as incompetent as the teaching staff.  Quinn considers "cool guy" Loren Payton to be his best friend, but it is mostly a one-sided friendship.

Recurring

 * Sonya Eddy as Tammy, the secretary to Principal Quinn. She is often the only sensible person in the school, but is largely ignored and ridiculed. Tammy and Loren Payton have a strong mutual dislike.
 * Kyle Kinane as Rod Knorr, an alcoholic teacher at Smoot. He is rarely sober at school, other than a few short stints of abstinence, and often gets caught up in the schemes of the other teachers.  Billy Shoemaker dated his mother, Doris, until her death, which really bothered him. Often distills crème de menthe and is a big fan of Señor Frog's margaritas.
 * The Sklar Brothers as Drs. Rick and Astor Green, a pair of twins who often take turns pretending to be the same school physician.

 * Mary Lynn Rajskub as Summer, the drama teacher who is slightly unhinged.
 * Peter Stormare as Superintendent Carson, the district superintendent who unsuccessfully attempts to run for mayor of Denver.
 * Cheri Oteri as Cattie Goodman, a "fixer" for the school district who is assigned to replace Quinn as principal after his arrest. She is a devout Christian and is constantly horrified at the gang's antics, which eventually drive her insane.
 * Patton Oswalt as Gil Nash, a real estate developer who is elected mayor and is revealed to be sabotaging the school so he can tear it down and build condos on the land.
