Okay. The FUCK? Their restaurant has just been robbed and Linda cares more about her reviews? On that note, the robber is actually CAUGHT and she's put out cause now he can't star in her show? So Bob has to make it up to her?
Actually, this may be hard to believe but, to answer the first portion of the question, if a business has been robbed, it could affect the number of customers and how well the business stays afloat. Case in point would be that some businesses have either closed or moved after a robbery.
How is Tabitha Johansson (a.k.a "Oil Spill" Girl) a parody/tribute/Take That! to Tori Amos?
The way she stands up and leans into her piano as she plays it, and the breathy way she sings. You have to be a Tori Amos fan to get it.
The song Oil Spill is also a straight parody of "Icicle" which is a Tori Amos song, clearly with overt sexual overtones, see for yourself: http://bit.ly/28W3iih
Why do the kids call Jimmy Jr. Jimmy Jr? They aren't on a first-name basis with his dad.
Because a lot of times kids who are a Jr, III, IV etc are referred to something different than their father at home, and they get used to it. It's entirely possible Jimmy Jr. always goes by Jimmy Jr.
I just noticed something... Why aren't the characters drawn with teeth... but the zombies in Tina's dreams are?
You don't see the characters teeth because their gums are in the way. On corpses, the gums are pulled back due to dehydration and decay, exposing their teeth
Gene being in middle school is already a stretch but Louise? Or is it an elementary school that goes up to grade 7?
Uh last I checked, both Gene and Louise are eleven and nine, an age where, in some cases, children might be attending middle school or so I think from experience, as I've attended middle school when I was ten, a year older than Louise and I've had a few friends who was nine and eleven when they've attended. It's kinda regional thing.
It's pretty clearly not a middle school. A lot of kids go to the same school from first to eighth grade.
The deformities on Mr. Goiter, Lady Big Nose and Henry Human Feet are pretty obvious, but what exactly was unusual about Mr. Down There Hair?
Presumably, that horse had some weird production flaw that moved his tail to his crotch, making it look like he had long pubic hair.
Bob's clearly a great cook, but terrible everything else. Why doesn't he become a cook in another restaurant? He doesn't look an especially enterprising type, for whom being his own man is an end goal.
The main appeal of cooking for Bob is getting to invent his own burgers, something he wouldn't get to do as just an employee—hell, he left his dad's diner over it. Being his own man may not be something he strives for, but the creative freedom that comes with it is.
In one episode Bob's wealthy friend invests in the restaurant only for Bob to chase him away when his creative vision becomes compromised. Expression and independence are more important to Bob than success.
Tina and Gene even thinking of voting for Millie in "The Millie-Churian Candidate" makes no sense! They also were trapped in the fort during "Fort Night", and thus know full well that Millie is certifiably nuts. It can be somewhat hand-waved in the case of the Pesto twins, who were also there and also stated to be voting for Millie but are also Too Dumb to Live most of the time, and Daryl, the other victim of Millie's fort prank, doesn't show up in this episode. But Tina and Gene are usually at least a bit smarter than that!
This might be more on a case of Millie being so similar to Louise, as they do tend to go along with what she does, so it's not that farfetched.
How does Bob not know that turkey burgers exist when he specializes in burgers?
I think the joke is that Bob claims turkey burgers don't exist because he believes a burger needs to be beef to be a burger. It's a "I have no son" kind of statement.
How is Bob in such terrible shape? He works on his feet, isn't noted to have a terrible diet, and doesn't seem to overindulge. People can totally be overweight in that situation, but he's usually floored by a little exertion or a mild injury.
I think that's because of those things, however, the other bit to that would be that we haven't really seen him exercise.
