responsibilities and choose to drink instead. Paddy's is only able to stay in business because of Frank's financial backing, government bailouts and tax fraud. In addition, money is saved through paying Dee less than minimum wage, and, at one point, "getting some slaves." Cast and characters The show features a core cast of five characters (The Gang) and a recurring cast of colorful side characters, including the Waitress, Cricket, the McPoyles, the Ponderosas, the Lawyer and various family members like Mrs Kelly, Mrs Mac and Uncle Jack Kelly, who cross paths and interact with the Gang in increasingly unhinged ways as the show progresses. Main Charlie Day as Charlie Kelly, co-owner and janitor of Paddy's Pub. He is a childhood friend of Mac, and high school friend of Dennis and Dee. He lives in squalor with Frank in a run-down, vermin-infested apartment, and has deep-seated psychological problems, partly due to substance abuse from huffing paint and glue, and partly due to his complicated family background possibly involving child abuse. He has an extensive history of pica and regularly eats various items not meant for human consumption, such as cat food, stickers, paint, and bleach. Due to his general lack of intelligence and his illiteracy, he is arguably the simplest member of The Gang. Despite this, Charlie is a naturally gifted musician, a self-proclaimed expert in "bird law" and possibly the only competent worker at Paddy's with his knack for unorthodox maintenance practices ("Charlie Work"). He also has an unhealthy obsession with "The Waitress", a recurring character who finds his interest in her creepy. Glenn Howerton as Dennis Reynolds, co-owner and the main bartender of Paddy's Pub, in addition to being Dee's twin brother and Frank's son. Originally the most intelligent and normal-seeming of the three co-owners, Dennis is slowly revealed to be the most narcissistic and psychopathic of The Gang. Dennis is extremely superficial, selfish, vain and abrasive. His predatory nature is often depicted through numerous attempts to seduce various women; which, when successful, result in him gaslighting and emotionally abusing them in order to win over their favor before inevitably dumping them once he has had sex with them ("The D.E.N.N.I.S. System"). It is strongly hinted at times that Dennis may secretly be a serial killer, though this remains ambiguous as a running gag. In season 10, he is diagnosed with borderline personality disorder, though he frequently denies this
