It's Always Sunny in Algeria

Between all of the complete and utter disregard for other's emotions in the show, It's Always Sunny in Philadelphia, one can already draw parallels to the individualist sense of self that Meursault has in The Stranger. 

One character in specific though, Dennis Reynolds, shows the complete embodiment of Meursault's self absorbed actions. Self absorbed in the best sense of the word. Because he follows his true feelings and disregarding others. Dennis is the part owner of a failing Irish pub with his sister, estranged father, and incompetent friends who he treats as though he does not know. Moreover, just like Meursault, Dennis is filled with passion and desire about the simple pleasures of the world such as sex and smoking (in Dennis's case, Crack). 

While Dennis is much less moral and has a desire for control over others, and his lust extends unto those who do not want it, he still follows the same ideology as Meursault. That ideology being a sense of self worth, and following ones own desires rather than societies rules. Although Dennis is shunned by society for his short-comings, like Meursault, Dennis continues to act as an outsider, and is often punished for it. 

Although Dennis's shortcomings might be more modeled off a modern day society, there are very strong parallels between his own life ideology and that of Meursault.
