What happens when you throw a yellow rock into a purple stream? It splashes. (Ba-dump-bum.) Grant and Martha share this and other favorite riddles, some with deceptively obvious answers.

Why do we pronounce bury like berry and not jury? The word originates in the Old English term byrgan, and the pronunciation apparently evolved differently in different parts of England. Grant explains why many terms go mispronounced if we read things without hearing them out loud.

What do you say when you answer the telephone? On the NPR science blog, "Krulwich Wonders," Robert Krulwich notes that hello did not become a standard greeting until the mid-19th Century, when the Edison Company recommended the word as a proper phone greeting. Before that, English speakers used a variety of phrases depending on the circumstance, from hail to how are you? One thing's certain: If we'd followed Alexander Graham Bell's recommendation, we'd all be greeting each other with "Ahoy!"

A riddle, a riddle, I suppose, a thousand eyes and never a nose. Nothing shakes up the dinner table conversation like a good potato riddle!

Greg Pliska, musical director for the Broadway show War Horse and our very own Quiz Guy, has a puzzle about Animal Hybrid Phrases combining two common expressions involving animals. For example, what do you get when stuffed animal stocks go down? A Teddy Bear Market.

Ever had golden catheads for breakfast? A native of Tennessee wonders about the origin of this term meaning "biscuit"--specifically, ones that are light, fluffy, and about the size of, well, a cat's head. Martha explains how the names of many foods derive from their resemblance to other things--a head of cabbage, for example.

A listener has spent the last 30 years looking for the origin of the playful phrase "you're the berries." This affectionate expression first appears in literature in the 1908 book Sorrows of a Showgirl, then made its way into popular slang by the 1920s. However, it seems to disappear during the next decade, and it remains only as a relic heard in the vernacular of those who lived during the era.

Should we use try and or try to? Merriam-Webster's Dictionary of English Usage says it's grammatically permissible to try and go to the store, or to ask someone to try and speak up. However, a fan of formality ought to stick with try to. Still, Grant warns against trying to force logic on the English language by creating rules that don't exist.

Whoever makes it tells it not. Whoever takes it knows it not. Whoever knows it wants it not. What is it? Martha shares this old riddle.

The question of how children acquire language has long intrigued parents and scholars.  MIT cognitive scientist Deb Roy recently found a novel way to study what he calls "word birth."  He wired his home with cameras and microphones, and recorded his infant son's every utterance as he grew into toddlerhood. He then combined the 90,000 hours of video and 140,000 hours of audio into some astonishing montages. Dr. Roy shared his findings at a TED conference.

If you're fair to middling, you're doing just fine. A native of the Tennessee mountains wonders about the origin of this phrase her good-humored grandfather used. As it turns out, fair to middling was one of the many gradations a farmer would hear in the 19th Century when they'd bring in their crop--usually cotton-- to be priced and purchased.

Is the phrase whether or not redundant? Well, take this sentence: "Whether or not you like it, Martha is dressing as a ballerina." Would that sound right without the or not? Now, the or not is technically redundant, but depending on the case, it's best to pick the wording that won’t distract the reader or listener.

Only the grass dies when elephants fight. This Liberian proverb is a reminder that it's the powerless who suffer when governments or factions fight.

If Sam and them are going to be here after while, can the "and them" mean just one additional person? In some parts of the country, it could be Sam's wife, or Sam's entire softball team. A listener from Texas shares this charming colloquialism.
