12 Best It's Always Sunny In Philadelphia Guest Stars

It was really only a matter of time before Dennis started a cult. However, few would have expected that cult to have formed on the basis that Mac kept steeling Dennis’ Thin Mint cookies.

‘Ass Kickers United: Mac and Charlie Join a Cult’ is the season 10 episode in which we see Charlie and Mac follow the life improvement teachings of ‘The Master’. Dennis’ fake teachings initially prey on Mac’s physical insecurities, but are subsequently hijacked by Dee and Frank for their own personal gain.

As a result, the cult mutates and intensifies with Dax Shephard playing a particularly unwitting member. By the end the gang have lost control of their cult, with Shephard continuing to follow their orders religiously (or the fake cult equivalent).

Shephard may have starred in the poorly received Employee of the Month, but there’s absolutely no doubt that he would be Cult Member of the Month… if it wasn’t a fake cult…or if cults had a ‘Member of the Month’.
