First, the innocent part of the explanation is that they have lots of items to get through and not much time, so talking fast is just about efficiency. But as for why they speed it up to the point where you can barely tell what they're goddamned saying, it's at least partly to shut down your brain's ability to think too hard. The executive director of the Ohio Auction School (one of a couple dozen schools that train auctioneers) thinks it has something to do with mindless compliance, rushing the decision and filling any possible moments of silent contemplation. That sounds more like an admission of guilt that an origin story, but I see that Slate got the same answer talking to a member of the National Auctioneers Association. Talking fast lends a (sometimes false) sense of urgency to paying $2,000 for prized horse cum.
As for what they're saying, auctioneers randomly throw in words like "dollar" or the phrase "would you give" or just the price repeated a bunch in succession, serving no real purpose other than to keep the rhythm going or to lull you into a kind of nervous trance so you won't think twice about buying a knife carved from the bones of a Confederate soldier.
Why Do Letter Grades Skip E And Go Straight To F?
The first four letters of the grading system make sense. We begin at the heights of the letter A, the shining trophy of excellence we all aspire to obtain. B, slightly less so, but still appreciated. C is where we're going to find our future comedy writers. D means the wheels have nearly come off the wagon, but luckily, disaster was averted. And then we skip E for no discernible reason and go directly to F, which people assume means "Failure," but that's idiotic if none of the other letters stand for anything.
Is there a reason we skip E, other than to teach our children a lesson in how you shouldn't expect too much from a poorly funded bureaucracy? Well, at one point, the American grading scales did in fact go A to E. The disappearance of the E and its replacement with F as if we're supposed to believe it's the same letter and don't try to tell me I've been imagining that little stick on the bottom this whole time, can be traced back to Mount Holyoke College in South Hadley, Massachusetts. In the late 1800s, the school's administration added an F so there'd be six levels (so E became what used to be around the D range).
The change caught on, but by 1930, most schools in America had eliminated the E altogether, because they thought six grades were too many and they were worried students and their parents would assume an E stood for "excellent." By the way, there's no record of any significant number of people misunderstanding the other letters. People could've just as easily assumed A stood for "Amazing," B stood for "Badass," C stood for "Crappy," D stood for "Dipshit," and F stood for "Fucking Idiot," but they didn't. Teachers were afraid people would see an E and assume they were geniuses, which I guess says a lot about why they were E students to begin with.
