Top 10 It's Always Sunny In Philadelphia Episodes

Boasting an impressively well choreographed, single-shot scene in which Charlie distracts a health inspector while the rest of the gang try to hide their newest, messy scheme from her in a series of near misses is genius. The repetition of jokes is played perfectly, especially Dennis' Matthew McConaughey impression, with Charlie's fast-talking explanations incredibly well written and performed.

As the gang try to exploit airline miles using chickens and steaks, and Charlie panics about the state of the bar, the viewer is dragged in to Charlie's undoubtedly filthy shoes and brought along on one of the busiest days of the illiterate janitor's life. This episode does such an amazing job of making the audience feel as unappreciated as Charlie, and as out of the loop as he is with the rest of the gang's insanely convoluted scheme.

Seeing how disinterested everyone else is in Charlie's work, despite the audience knowing its importance, perfectly sums up all of their characters, with Charlie even finding time to rig a stool to be used as a final gag despite his panicked and stressed state. This is arguably the most technically brilliant episode of the entire series and well deserving of its place as the runner-up in this list.
