When Hank goes to buy an "L pipe" at the Mega Lo Mart, his truck is parked in the middle of the parking lot and nothing in between the middle of the cars. As Hank is about to leave in his truck there are concrete blocks ahead of his car (with a sidewalk next to them). Also if you look at the car behind Hank's truck before he is about to leave it is a white color. Whilst he is reversing it is now a dark blue color.
Whilst the guys are waiting in the alley for Hank to get back (before Boomhauer leaves) you can see the backhoe is behind Boomhauer. When it changes to showing the empty street from their point of view, the backhoe is now down the street. The following shot its back to behind Boomhauer.
Hank finds Dale and Bill in the hole and as he's rescuing them Hank says, "Well you haven't moved in about 50 hours?" Hank found out they were missing when the guy who rented the backhoe comes looking for it and Hank is surprised to find they have gone missing. Seems a bit odd no one noticed them missing or decided to report it over 2 days. Whilst Bill lives alone and maybe no one would have noticed, Dale's wife and son would have noticed after that length of time. Despite Nancy still having an affair with Redcorn, there is too much evidence throughout the show's history that show both she and Joseph were constantly concerned when anything happened to Dale.
Dale and Bill say that Hank said he'd be back in a minute, but he never did. He just said he'd go with Hal.
The tagline for this episode is a clip of Dale saying the name of a planet by rolling his tongue, spitting, then gulping.
This episode marks the first mention of Spapeggy and Meatballs.
When Hank first pulls up to the street when looking for Bill and Dale there is no sign of wreckage on any of the streets, but then when it shows his POV looking down all the streets, suddenly one street has been damaged.
In the scene where Bill is trying to open the beer can with the backhoe, he rips up the pavement with it. As Hank sees the mess he gets in the machine and pushes the pavement back that Bill tore up. When Boomhauer comes along you can see his foot falls into the hole and gets stuck even though Hank pushed it back. Also if you look the soil Bill dug up has disappeared when Boomhauer comes along.
After Hank helps Bill and Dale out of the hole they fell in, Hank's truck is nowhere to be found.
Hank : No, that's a straight pipe. I'm looking for an L pipe.
Teenage Employee : L's are straight.
Hank : Lowercase maybe but...Okay, fine, I'm looking for a capital L pipe. It bends on a right angle.
Teenage Employee: Pipes don't bend. All pipes are straight.
Hank : All pipes can't be straight. If they were, your department store wouldn't be selling those U pipes right behind your shoulder.
Teenage Employee: Those aren't pipes.
Dale: You said you'd be back in a minute. We waited a minute. Then we waited another.
Bill: Then after about a million minutes, I forgot why I was counting.
Dale: An exterminator in a pet cemetary! I have many enemies here.
Dale: You're lucky you're in the army. You've got a tracking device in your teeth. They'll find you.
Dale: Hank, you were right about it being complicated but wrong to make me want to try it so badly.
Dale: I am the hoe-master! Hear me hoe!
The song Hank and Hal sing (and is later played on the radio) is "The Gambler" by Kenny Rodgers. The song Dale sings as Hal and Hank leave the music store is "Highwayman" by The Highway Men, a group consisting of Kris Kristofferson, Johnny Cash, Waylon Jennings, and Willie Nelson.
When Hank and Hal go to the sports shop that revolves, it is an reference to the restaurant that revolved in the episode, "As Old as the Hills (1)". Hal even refers to the shop as having used to be a "restaurant."
This episode was originally supposed to contain a B story where Cotton puts his baby up as collateral so he can test-drive a new car. The plot (and guest voice Dwight Yoakam) was dropped due to lack of time.
The episode title is connected to the NIMBY phenomena or "not in my back yard" attitudes that arise in relation to the location of necessary but unpleasant facilities like sewage treatment plants. Bill's septic tank was at one point believed to be literally "not in my back yard" but rather, he thinks, in the side yard. While searching, the back hoe destroys Bill's back yard. In the end Hank has learned that it is not such a good thing to have a friend who is not close enough to his back yard for sharing a beer.
