The Reason White Castle Slider Burgers Have Five Holes

While it’s not often mentioned in conversations about the best fast food burger on the menu alongside staples like Shake Shack or In-N-Out, the White Castle slider burger still holds a special place in the stomachs of those who enjoy their bite-sized convenience. In 2014, TIME even named the slider the most influential burger of all time, with its debut in 1921 helping begin our nation’s obsession with fast-service burgers.

Peel the bun off a White Castle burger and you’ll find the square meat patty has exactly five holes. Why? Thrillist writer Wil Fulton went looking for an answer to this gastronomic mystery. It turns out that the holes serve a very functional purpose.

In 1954, a Cincinnati-based White Castle employee named Earl Howell stuffed his location’s suggestion box with a note that said the patties might cook more quickly if they were pierced. The reason? The franchise steams its burgers on the grill, and the holes allow the steam to better penetrate the stacks of patties (usually 30 burgers tall) that are piled on the grill at one time. No one has to flip the burgers, and they wind up coming out of the kitchen faster. The steam also picks up the flavor of the onion acting as a bottom layer, allowing it to spread through the stack.

Howell’s idea soon spread from Ohio to White Castle restaurants nationwide. The company facilitates the creation of the holes by puncturing a “meat log” and then slicing it and sending the patties to locations.

If you enjoy their distinctive flavor, the holes have a lot to do with it. Enjoy.

The Reason Dogs Twitch in Their Sleep

The sight of a dog batting its tiny paws around while sleeping is irrefutably adorable, and it’s not hard to imagine that your beloved pet is dreaming of swimming, fetching a Frisbee, or bounding around the yard in pursuit of a scampering squirrel.

In truth, that’s pretty much exactly what’s going on. Dogs, like humans, dream during the REM cycle of sleep, and their twitches are responses to whatever’s happening in those dreams. Though all dogs can exhibit muscle movements while dreaming, PetMD reports that it most often affects younger and older dogs. This is because of the pons, a part of the brainstem with two “off” switches that regulate movement during the sleep cycle.

“If either or both of these ‘off’ switches is not fully developed or has grown weak due to the aging process, then the muscles are not completely turned off and during dreaming, the animal will start to move,” Stanley Coren, a neuropsychological researcher and former psychology professor at the University of British Columbia, told PetMD. “How much movement occurs depends upon how effective or ineffective these ‘off’ switches are.”

As long as your dog looks like it’s having a grand old time in its dreams, you can sit back and enjoy the show. If you think your dog might be having a nightmare, be careful about waking it up. As the American Kennel Club (AKC) explains, a dog woken abruptly from a bad dream might bite you before it realizes its distress wasn’t real.

You should, however, learn to recognize the difference between a normal dream and a seizure.

“Some [dogs] manifest dreaming with twitching, paddling, or kicks of the legs. These movements are often brief (less than 30 seconds) and intermittent,” Jerry Klein, the AKC’s chief veterinary officer, described on the AKC website. “Seizing dogs’ limbs, on the other hand, tend to be rigid and stiffer, with more violent movement.”

The seizure can also be accompanied by loss of bowel control. If that description sounds familiar, you should talk to your veterinarian.

The Reason Doctors Have Such Sloppy Handwriting

It seems counterintuitive that doctors—widely regarded as some of the smartest, most detail-oriented people out there—so often have horrible handwriting. From a patient’s standpoint, it could seem downright terrifying. If your pharmacist misinterprets your trusted physician’s chicken scratch, you could wind up with a dangerously high dosage of medicine, or even the wrong medicine altogether.

In 2006, the National Academies of Science's Institute of Medicine estimated that doctors’ sloppy handwriting was killing more than 7000 people per year, and preventable medication errors were harming around 1.5 million Americans annually. Many medical offices have since switched to electronic medical records and prescriptions, and some states have even required them to do so.

But that doesn’t tell us why doctors’ penmanship is so poor in the first place. One reason is because doctors have to write much more than we realize.

“In the medical field, if it’s not documented, it didn’t happen,” Celine Thum, medical director at ParaDocs Worldwide, told The Healthy.

If you’re the very first patient of the day, the record of your visit and any prescription slips you get might be perfectly legible. Ten hours and dozens of appointments later, however, your doctor’s hand muscles are probably pretty cramped.

The content they’re writing isn’t particularly easy to spell, either. If a doctor is jotting down glomerulonephritis, for example, they may not stop to make sure all those vowels are in the right places.

“We have so many technical terms that are impossible to write,” Thum said. “You sometimes scribble to cover the error.”

However, if a prescription looks indecipherable to you, it’s possible that your doctor is using shorthand that your pharmacist will immediately understand—like the abbreviation QD, from the Latin phrase for “one a day.”

If you’re confused about what the doctor has written on your prescription slip, you can always ask them to clarify aloud, and double-check that it matches what’s printed on your prescription bottle.
