10 Best It’s Always Sunny In Philadelphia Characters Only In One Episode

Dee's Therapist, played by Kerri Kenney, is one of those guest stars who makes their episode incredibly memorable without being all that memorable themselves. That sounds like a criticism, but it's actually an very important role, and one not every character could fulfil.

Indeed, there are some characters who miss out here because they so aggressively hog the spotlight and don't give the Gang room to breathe. Dee's therapist, though, allows the Gang to bounce off her brilliantly, all while keeping a straight face. Considering Dee is literally screaming in her face and smashing plates around her by the end, keeping her composure is no mean feat.

Each of the Gang is analysed in turn, and we get to see how each of them handles it. The therapist is the vehicle for some all-time great moments, so has definitely earned a spot in the guest star hall of fame. Through Mac & Charlie, we see a somewhat realistic therapy session that delves into their personalities and their place in the group. Dennis is his usual hyper controlling self and Dee, despite it being her regular therapist, the most defensive.

It's Frank and his complete breakdown which steals the show though.
