This is the best episode of the show ever. I have seen every episode and this is the best. There are a lot of great episodes to choose from, but, I think this really is the definitive episode of It's Always Sunny In Philadelphia. If you are trying to introduce someone to the show it is a great one to choose. It showcases every character at their very best. We see Dennis be a total psycho, Mac be sexually confused, Charlie as a charming fool, Dee as annoying, and Frank as a scumbag. The scene with Pepper Jack is especially hilarious. This showcases everything great about Sunny. The show has famously been described as Seinfeld on crack. Episodes like this are exactly why.
