Your knuckles know more than you think: Here’s what they can tell you
Published on April 22, 2026
You might forget where you left your keys or your glasses, but some things are forever imprinted in your memory one way or another. And for those things you simply can’t seem to remember, some useful mnemonic devices can help you. For example, how can you remember the presidents on our bills? And what about all the spelling rules our language has? Is it "gray" or "grey"? Don’t worry, we’ve got you covered. Keep reading and learn a few tricks.
The faces on US bills
You may handle bills every single day, but can you answer whose face is on each one? You don’t need to remember; this mnemonic device will do it for you: The phrase "When Jeff Left Home, Jack Got Fat" gives you the answer. As you can notice, the first letter of each word stands for the last name of the president or founding father: Washington, Jefferson, Lincoln, Hamilton, Jackson, Grant, and Franklin.
Knuckle months
Yes, we keep lots of calendars, but sometimes we have to double-check if a month has 30 or 31 days. Has this happened to you? If it has, next time you’ll want to use your knuckles. The rule is simple: Make two fists and count across your knuckles and the dips between them. Months that land on knuckles have 31 days. The dips are the shorter months, February being the shortest, naturally.
"Righty tighty, lefty losey"
Have you ever had to try a few times before knowing whether you were loosening or tightening that screw? Well, with this rhythmic phrase, you won’t need to do that anymore. If you turn right, you’ll be making it tight. On the other hand, if you turn left, you’ll loosen it.
Gray or Grey?
English spelling keeps everyone on their toes, and certain words have regional rules that make everything worse. Nobody can remember them all, so this device comes in handy. When you don’t know whether it is "gray" or "grey," think of it this way: Gray, with an A as in America. Grey, with an E, as in England.
How to spell "necessary"
"Necessary": This is another word with a spelling that can create a few problems. And the mnemonic device for this one is picturing a T-shirt. You know how a T-shirt has one "Collar" (that’s one C) and two Sleeves (that’s two S)? That’s it, spelling solved.
"HOMES" of the lakes
Back in school, memorizing the Great Lakes could feel like a geography pop quiz. Simply the word "HOMES" is a trick that many teachers share with their students. Why HOMES? Because each letter represents a lake: Huron, Ontario, Michigan, Erie, and of course, Superior.
"My Very Educated Mother Just Served Us Nachos"
Just as with any other long list, remembering the order of the planets in our solar system is no piece of cake. But this fun phrase has the answer to your prayers, it’s not bout nachos, but about the names of the planets in order: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
"Never eat soggy waffles"
This one sounds like breakfast advice, but it’s actually a compass lesson. The first letters match the four cardinal directions in clockwise order: North, East, South, West. Many kids learned this one in school, and plenty of adults still repeat it quietly when trying to picture a map in their heads.
Left or right?
This may sound silly, but many people struggle to point left; most need more than just a second to figure out which one is actually left. But many have discovered something quite useful: hold up both your hands and use your thumb and index finger to do an "L." Can you see which one forms a clear letter? That’s left, of course.
"Large Elephants Jump Slowly And Sink Rapidly"
Is this connected to the Constitution? Yes, it is. Civics teachers sometimes lean on this unusual sentence to remember the seven articles of the US Constitution. Each word stands for one: Legislative, Executive, Judicial, States, Amendment, Supremacy, and Ratification. Now you just have to remember this funny phrase.
