They Got Chops/Poetic Injustice/Comedy of Feathers

Production code: 412

This is the episode of the revived series that Genndy Tartakovsky was involved in, other than the theatrical short "Chicken Scratch".

Even though this is the final aired episode, "2Geniuses 2Gether 4Ever" was actually the final produced episode, similar to how "What's the Big Idea?", "Octi Gone", "Destination Imagination" and "Goodbye to Bloo" were the final produced/aired episodes of "The Powerpuff Girls" and "Foster's Home for Imaginary Friends".

This wasn't going to be the series finale yet, this was supposed to be a foreshadowing of many elements to follow the three final produced episodes featuring Mandark, "Babe Sitter", "Mountain Mandark" and "2Geniuses 2Gether 4Ever".

It were the three last times when Dexter is not in his lab yet in this episode, even though Mandark starts to take over the show and made three of the episodes about him.

It is rumored that Dee Dee has been rescued from the Zoo in the next produced episode "Babe Sitter", because of that, it was aired out of order.

When Dee Dee said, "Lions, Tigers, and Bears." and Dexter said "Oh My." This was a reference toThe Wizard of Oz.

It's referenced in the episode "Babe Sitter" when Mandark has used a girl's brown hair.

This is the last episode when Dexter in Love.

Though this episode aired as the Season 4 finale of this show, it is actually the 77th of the three produced episodes of Season 4, creating a continuity error in the American broadcast.
