"Lost in Myspace" features Strickland Propane getting a MySpacepage for the company. While it comes across as dated for 2008 (and a sign that the show writers are trying to stay hip and relevant, even though it's years past that), many Southern and Western towns in the U.S. like Arlen in real life are a bit behind the times and would embrace trends like MySpace after everyone else has moved on to the next thing.
And considering how long an episode takes to be produced, MySpace was still somewhat popular in 2007 and only started declining in 2008.
Considering Dale is shown to be a bad shot, his threatening a suicidal Bill with a gun as seen on "Pretty, Pretty Dresses" would be effective since he wouldn't likely kill Bill. (Although it also could just be the shock of how willing Dale is to resort to such measures.)
Bill mentions several times he had Abusive Parents, and the only woman he ever loved left him. Hence it's no surprise that the minute anyone gives him an inkling of positive attention ("A Bill Full of Dollars") or authority ("Apres Hank, Le Deluge") he lets it ALL go to his head.
In "Wings of the Dope," Buckley's angel has wings but no halo throughout the episode. As he walks toward the horizon at the end, he pulls a halo out of his pocket and puts it on - he earned his halo for giving Luanne closure and helping her find a better path in her life than beauty school.
In "Kidney Boy and Hamster Girl," the porta-potty Hank's in falls apart, revealing him to be a squatter. A few seasons before in "Hank's Unmentionable Problem" Dale suggests to Hank to squat to help his constipation. Either the former is a coincidence or Hank took Dale's advice for a change.
In some earlier episodes, Bobby only goes up to Hank's stomach while in other episodes he's taller and comes up to his shoulders. Although Bobby never hit puberty in the series, he is 11 when the show starts and is 13 by the time the series ends, and this can be explained by him having a small growth spurt.
Could also count as Fridge Horror: In "Keeping Up With Our Joneses" when Bobby is caught smoking, Peggy warns him it will stunt his growth. Bobby becomes addicted to cigarettes for a short time after Hank made him smoke an entire carton of cigarettes as punishment, and since Joseph and Connie hit puberty and aged quicker than Bobby, Peggy may've been right.
In "Rodeo Days" Bill recognizes the clown is Bobby due to Bobby wearing Bill's underwear and Peggy's shoes. His underwear did go missing but he recognized Peggy's shoes because he has an unrequited crush on Peggy and would notice small details like that (plus, Peggy is a woman with size 16-and-a-half feet. You'd have to be blind or really oblivious not to notice).
With the naivete of Hank and Peggy about drugs, prostitution, and other vices of the world (with Hank trying to keep his son from knowing about it, as seen in "Get Your Freak Off"), it's a damn good thing Bobby is more street-smart by comparison (mostly by having friends and hanging out with people who know more about the way the world works more than he does, even if said acquaintances turn out to be a bad influence on him) or else he'd probably get into way more trouble than he usually does.
In the episode when Bill gets involved with a bunch of over-enthusiastic body builders in order to get in shape for his army physical, he injures himself after putting on too many weights for a work-out machine. We don't know exactly what injury the machine caused until the end of the episode. The doctor states that Bill had ruptured his rectum, causing his internal systems to become external. It's called rectal prolapse and it's exactly as unpleasant as it sounds and a common hazard with bodybuilders.
In "Yankee Hankee" Hank asks his parents for his birth certificate. Why would he be getting it from them in his forties? Wouldn't he have needed it for things like getting a job, a passport, etc?
How come Social Services were called when Bobby got a black eye but not when he was forced to live in a dog house?
One, Bobby was living there voluntarily. Two, the social worker (Anthony Page) was sent back to Los Angeles after he screwed up the child abuse investigation by not talking to the Little League coach (who is friends with Page's boss) to see if the black eye was from an accident during the gamenote though Page was brought back on the episode "Junkie Business" as the social worker for the drug addict who tried to claim disability so he can work at Strickland Propane.
And three, Hank and Peggy repeatedly begged Bobby to move back into the house.
What was George W. Bush even doing campaigning in Texas? The way the Electoral college system is up, candidates pretty much never campaign in their home state and leave places like Texas, New York, and California alone in favour of pushing their presence in "Swing states" like Ohio, where citizens votes count more.
