"If you leave your vehicle's engine running during a delay in proceeding (traffic-jam, road construction, accident-resolution, "stuck" red signal-light, etc.), you will be sitting there for many minutes, just wasting gas. The instant you turn the key off and climb out of your seat to stretch, however, THAT'S when the line of traffic will begin moving again, and thus you will have shut off your engine "for nothing", AND you will now be holding up everyone behind you while you hastily hop back into the driver's seat and re-start the engine so that you can move forward again."
I finally took da plunge and bought a second-hand Toyota Prius because I'd eventually had one too many cases of Murphy's Law of Engine-Idling Duration... the Prius automatically shuts down its power during stand-stills, and then uses its electric motor to provide instant mobility as soon as you're ready to go again.

Da "hanged if you do and hanged if you don't" fact-of-life irony regarding how a sizeable sector of da female populous treats any dude who shows interest in them romantically --- i.e., if a guy gets da idea from a gal's attitude/behavior towards him dat he should just mind his own business and not court her, she'll bawl and blubber dat he is making her feel ignored and unvalued. Yet if he then hastily begins persuing her in da naive belief dat this is what she wants, she'll go "bawlin' and blubberin" to da COPS and tearfully accuse him of harassing her! Can't win... :P
I always tread super-carefully when approaching a new lady for companionship or intimacy --- seems like Murphy's Law of Attentiveness is often lurking just around da corner to pounce on me and give me undeserved grief!

"You can struggle for hours to get bearably comfortable --- i.e., warm enough, free of aches, etc. --- but then just as soon as you actually DO succeed in getting comfortably 'settled in' at long last, something unavoidable will come up dat will force you to relinquish said comfy position to go and tackle some disagreeable physical activity which will cause you to get chilly again, experience more bodily pain, etc."
Two "sister" examples of Murphy's Law of Getting Comfortable would be "Murphy's Law of Falling Asleep" (i.e., you can struggle for half the night or more to fall asleep, but then immediately after you finally drift off, someone or something comes along to wake you up again) and "Murphy's Law of Personal Comfort" (i.e., however comfortable you become will be in direct inverse proportion to da comfort of others in your vicinity; for example, da nearer you sit to a heater/air-conditioning duct, da more you will block da flow of said "moderated" air, and so while YOU YOURSELF may indeed feel more-tolerably warmer/cooler, EVERYONE ELSE in da room will feel even more uncomfortable than you would have if you'd sat a more-reasonable distance from said climate-control orifice. Or if you recline your seat on a public-transportation vehicle, said tilted-backwards back-rest will encroach on da extremely-limited "personal space" in front of da passenger seated behind you).

Refers to the infuriating situation of something you need's usually being at the bottom of a pile, at the back of a drawer/shelf, etc.
I have a 2--vertical-layers-deep stack of plastic totes for storing my DVD-collection, arranged in alphabetical order. It's often the case that the disc I want to watch has a title that is near the end of the alphabet, though, and so I hafta laboriously remove all da rest of da crates to access the very back/bottom box... yep, a classic case of Murphy's Law of Accessibility!

"You can stroll a store's aisles till Doomsday and never spot da item you want, but then, just as soon as you interrupt a staffperson to ask for help in locating said desirable, THAT'S when you will notice your sought-after item right off!"
While stocking up on food at a Super Walmart, I was looking for larger packages of Armour Vienna sausage so that I could save a few cents per can, but although I had thoroughly searched the surrounding areas on the shelves, I still hadn't found anything bigger than the small six-packs, so I finally asked a nearby employee if there were any of the larger packages in stock, possibly in the back room. Well, just as we were both walking back to the area of the aisle where I'd been looking, THAT'S when I finally spied the 12-packs that were sitting on the very top shelf! Guess that was a classic case of Murphy's Law of Customer-Assistance... ah, well, again, the 12-packs were indeed sitting very high up, so at least that was a plausible excuse for my not having seen them before, especially since the store usually doesn't even expect its customers to notice stuff that's placed 'way up there, anyway; that "lofty" location is merely where they store extra merchandise for replenishing the lower-down shelves when the stock there starts to run low.

"You can patronize the slots till Doomsday or buy any number of scratch-off tickets and never gain any significant winnings, but then just as soon as you stop playing, the very next player will win big."
Many an addicted gamer believes in Murphy's Law of Gambling, even though it is indeed :"all chance" and thus seldom actually works out that way.

"You can sit around at home till Doomsday and the prices at the pumps will stay fairly low, incessantly tempting you to travel. But the moment you decide to take off somewhere and head out on your trip, the price for a gallon of gas will go right through the roof!"
Gas-prices seemed fairly "stable" all summer, and so I delayed a road-trip for a while to "save up" or "accumulate" a number of errands so that hopefully my trip would be more cost-effective with regards to gas-consumption, but then when I stopped to fill up my tank in the morning when I was first heading out, the price had suddenly jumped over a quarter higher per gallon! Sounds like a classic case of "Murphy's Law of Gasoline Prices" to me!
