"Charlie Kelly: King of the Rats" is the tenth episode of the sixth season of It's Always Sunny in Philadelphia.
10:00 AM on a Tuesday, Philadelphia, PA
In the bar, The Gang are talking when Charlie comes in, zoned out from bashing rats in the basement. He proclaims he killed a nest of about 200 rats and wonders if a rats life is more important than a humans.

- The title picture of this page - it's a shot from the deleted ending scene for this episode.
- Frank had mentioned meeting people "down by the bridge" previously in "Mac and Charlie Die (Part 1)". Also, in "Mac's Mom Burns Her House Down" Frank was going to dump Dee under the bridge.
- A "little puppy", which Charlie was making outside of the bar, named Scarcoon ("Scary coon"): he is not able to kill the rats anymore, so he needs this raccoon just to scare them away.
- "A guy with a wormhat - like, his hat is made out of worms. And, like,
a little bird with human teeth" - all are products of Charlie Day's improvisation, which you can see in an extended scene of Mac and Charlie's brainstorming from "Mac and Charlie Write a Movie".
- David Gueriera ("Duncan") has previously twice appeared in the show as completely different characters: in The Gang Sells Out and The Gang Cracks the Liberty Bell.
- The opening scene where Charlie talks about killing rats is the scene that convinced Director Guillermo del Toro to cast Day in the role of Dr. Newton Geizler in the movie Pacific Rim.
