Probably some backroom shenanigans between Jonah Hill and people at a higher paygrade than Jonah Jill. (as MacFarlane and Sugar have shown, quality is not a barrier to taking off)

The actual answer is a lot more simple: no one watched this garbage. It pulled in some of the lowest ratings in the network's history, to the point that it caused Family Guy (which followed it) to begin losing viewers by the millions.

Imagine, a show so bad even people who like Family Guy find it beneath them. They said it couldn't be done.

It was a mean vicious little show that had no respect for the audience.

Every single character was unlikeable. Every joke fell flat. They expected it to succeed on edginess alone.

Family guy manages to have funny moments here and there, surrounded by an ocean of mediocrity and childish shock humor.

This show makes me want to take a whole bottle of Xanax.

completely repugnant twat?

But that's every one of them, this Mad Lib is terrible!

horse?

cartoon voice actor?

Sorry, "Kevin Keller", as in the ARCHIE comics gay character, designed to be a positive role model for gay youth but also a bland character in a gag comic universe.
