These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Base Breaker: Tammi is this. While she was initially introduced as a pleasant and compotent character who was sweet to Rusty, she would later suck the fun out of the series in any future appearances, with her enforced morals and demands for child support payment, while reminding everyone of how much it sucks to be a deadbeat dad.
Big Lipped Alligator Moment: At the end of the 9th episode, at the stadium, another Sheriff walks up to the real Sheriff and beats him to death with a club. It's never explained in the episode and just appears to be a random last minute gag. Another time, it shows Sheriff tied up in a chair, hopping to the Cuylers for help but is knocked out by another Sheriff. This is also never explained. However it is later subverted when it's revealed that there's an entire cloning farm of sheriffs, which is likely where that one came from.
Ga Ga Pee Pap "12 Gun" Cuyler towards his grandson Rusty in "Dead Squid Walking".
In both cases, and a few other unmentioned ones, and this cannot be stressed enough; No Yay.
Moral Event Horizon: After years and years of off the wall crazy drunken antics, Early managed to finally cross the line in "Gun of a Son" where in a drunken fit of rage he shoots Rusty in the face putting him in the hospital in critical condition and afterwards managing to pin the whole incident on his baby Grandson getting HIM arrested and thus getting off scot-free. Yeah you read that right, Early managed to get an innocent baby sent to jail, HIS OWN GRANDSON! AND critically injure his son (granted he's done it before but all those times it was Played for Laughs).
And good luck guessing WHICH of the many evil acts Dan Halen has commited count as him crossing the MOH. It might as well be ALL OF THEM!
