That would be “Better Be Right Or Your Great Big Venture Goes West - Get Started Now!” Whatever else (NSFW) could you possibly be thinking of? 
Four-twenties-fifteen. (More sensible, you must admit, if only marginally so).
I’m told that in parts of Belgium and Switzerland, they use the eminently logical numbers septante, huitante (or octante) and nonante for seventy, eighty, and ninety, just like the other Romance languages.
(Weirdly, a few dictionaries say that we do it in Quebec, too, but we completely don’t. We use exactly the same number system as France.)
But the only reason why there’s a distinction between “conventional current” and “electron current” in the first place is that someone got the direction of electrical flow wrong when assigning the “convention”. If we were starting from scratch today, with knowledge of electrons, there’s no way we’d pretend that electricity flowed in the opposite direction to the way the electrons flowed.
This does actually make sense. Almost everything is righty tighty, lefty loosey, because that’s the (arbitrary) standard. The exceptions to the standard occur for one of two reasons: First, some things are deliberately opposite of the standard, because there would be bad consequences for mixing them up with the more common things that use the standard. For instance, propane fittings have reversed threads, so that you can’t use a hose designed for water with propane. Second, some screwed things, due to their mechanical environment, would tend to loosen with use, if they were righty-tighty. This is often the case for wheels and related hardware of vehicles, which rotate forward much more often than backward.
AC Adaptors. Everything has one, they’ve all got different connectors on them, even when the voltage and current are the same. There’s almost no chance of reusing an old adaptor with a new device, but it’s pretty easy to hook up a WRONG one with a device and cause damage.
Why didn’t they standardize on a few different size/voltage/current combinations with interlocks years ago?
Chronos has it right. Look at the this picture of a wire wheel. There’s only one nut, in the center, holding the wheel onto the hub. There are splines along the hub (like this), but if those wear out, the act of driving the car would tend to unscrew the wheels on one side. They change the threads so the wheels would only come off if you drive backwards.
(My MG has octagonal knock-offs, instead of the winged one in the first picture. In the back, with the spare tire, are a large skate key and a lead mallet.)
Me being the rational type, I don’t like the name of the convention of “righty-righty, lefty-loosie”. Sure, most of the time we’re a bit above what we are trying to screw (heh,) but sometimes I have to think for a moment whether right means clockwise or counterclockwise, especially if I am under what I am trying to screw.
Now we have to think of mnemonic for Clocky In, Counter out.
Nope; conventional current in linear circuits is assumed to be instantaneous; once the circuit is complete, “flow” of “current” occurs everywhere in the circuit subject only to the action of time-varying impedences. Electron current flow is much, much slower. The convention–both of them, actually–are arbitrary, so there’s no reason they have to be different in sign, but no pressing reason that they be the same, either. The only people who really care are the solid state physicists and engineers designing transistors. Everybody else might as well be driving in America and England with no route inbetween.

It’s worth noting that English also uses the equivalent of “quatre-vingt”, although I believe it is now an archaism. Consider, for example, Lincoln’s “four score and seven years ago” speech.
Do you know which dictionaries that would be, so I won’t buy them? 
Turning your car’s steering wheel clockwise causes your car to turn right.
Well, at the begining of the day you clock in, and and the end of the day you count out. (The till that is)
Okay so it’s lame.
The Month/day/year convention for expressing dates of Americans, when lots of the rest of us use the day/month/year convention. Local bias of course, but my convention seems to me to be more rational - there is a logical progression from smaller units to bigger ones.
The difference is obvious when one sees dates like 7/28/07 (apart from the slightly vertiginous sensation of wondering what the 28th month is at first glance), but dates like 6/3/07 are inherently ambiguous and require a search for context which defeats the whole time-saving point of the abbreviated expression.
I have seen some people use a convention where they do day/month in Roman numerals/year (6/III/07 is now obviously disambiguated), but it hasn’t caught on.
That one is better than the American convention, sure, but year/month/day is the best one. Going from largest to smallest units, it mimics the hour/minute/second convention that we all use for time.
And there’s only one convention that starts with the year. There are two that don’t start with the year: M/D/Y and D/M/Y, leading to ambiguities like 01/03/02. (Speaking of which, why is anyone at all still using a two-digit year?)
Given that a century is longer than most people live, a two digit year is both compact and unambiguous for almost any daily date purpose. It’s rare that someone talking about a historical date uses a two-digit year, it’s just the sort of day-to-day stuff that we abbreviate.
Sure those whiny computers that get their digital knickers in a knot over it, but even that’s pretty much a thing of the past.
The whole 12 months a (solar) year with varying numbers of days per month (28, 29, 30, 31?), and different days of the week per date over the years. Why not 13 months of 28 days each? A week could stay 7 days, now every date will always be the same day of the week every year. In tribute to the Simpsons, the 13th month would be called “Smarch”.
Yes, that makes only 364 days. The 365th day is “New Year’s Day”, which is its own day between December 28th and January 1st, and not part of any month nor any day of the week, and is a holiday (but counted as the first day of the year for year counts: 28-Dec-2007 is followed by NYD-2008, or numerically 00/00/2008, and then 01-Jan-2008). For Leap Years, the day after New Year’s Day could be Leap Year Day (LYD-2008, or 00/01/2008 or 01-00-2008), also a holiday, followed by January 1st, which is, as always, a Monday.
Christmas Day would become December 22nd, a Friday – so no more having Christmas falling on a Wednesday. Independence Day in the US would get moved to July 5th so as to always be a Friday, or to July 1st to always be a Monday. Thanksgiving (US) is “the fourth Thursday of November”, so it would always be November 25th.
For financial statements that report “in quarters”, each quarter is exactly 13 weeks, ignoring New Year’s Day and any Leap Year’s Day.
Come on, who’s with me?
Thank you for your response. This was much appreciated.
The till–brilliant!
But at least you don’t have to cope with the English system of weights and measures still in use in the US. 12 inches make 1 foot, 3 feet make 1 yard, 5280 feet or 1760 yards make a mile, 4 pints make a quart, 4 quarts make a gallon, 4 pecks make a bushel, an acre is 4840 square yards, and none of this is based on any measuring unit that makes any kind of sense, all of it quite is quite arbitrary. We should have gone metric along with the rest of the world a long time ago.
My car gets 15,120 furlongs to the hogshead. Do the math.
I like your plan, but I’d adjust by having Independence Day stay on the 4th – it’s the 4th for a reason, first off, but more importantly, the holiday would always be a four-day weekend. We need more four-day weekends, not fewer. Leap Year Day should also be a holiday.
