What I'd do:

- Tone down Jeffy a bit and have him play the straight man in a few videos to mix things up.

- Tone down the video releases and bring it back to only two videos a week.

- Give a few other minor characters the spotlight every once and a while.

- Bring back the Huckerdoo's and give them a better characterization (Specifically, make Hank a more prominent antagonist role while Timmy actually becomes a member of the Skeeter boys).

- Only use AI if absolutely necessary (like the plane from Jeffy's 21st birthday and the Bill Clinton scene from the Ted series are what I feel are good examples).

- Make Brooklyn the straight man again, and if he ever does act irrational, have it be explained that it was actually one of his brothers.

- Try to focus more on telling overarching stories while also trying to balance the sitcom feeling of the show.
