A few things that annoy the heck out of me.
U.S. Coins and Bills
Since 1857, when the half cent coin was discontinued, the smallest U.S. coin has been the one cent coin, the penny. According to the inflation calculator, that 1857 penny was worth 23 cents in 2009 dollars.
When I was a young child in the mid-sixties, candy bars and packs of chewing gum were a nickel (I remember when they jumped up to a dime); now they're nearly a dollar. Back then we could buy small, individual pieces of candy for a penny, so pennies at least made some sense in a six-year-old's economy. But a February 2010 penny is worth less than 15/100 of a cent in 1965 currency. Trust me, no child feel the need of a 1/10 cent coin back then.
A February 2010 dollar is worth slightly less than 15 cents in 1965 dollars, so a 2010 dime is worth less than 1.5 cents. The dime is the new penny. (More precisely, the dime is the new 1947 penny, since that how far you have to go back to get exact equality using the consumer price index of February 2010.) Or, if you go back to 1857, when the penny was already our smallest coin, then the quarter is the new penny.
So we should at least get rid of the penny and the nickel, and possibly replace them with two dollar and five dollar coins, meanwhile getting rid of the dollar and five dollar bills. But if you think about it, having dimes and quarters but no nickels doesn't work very well. We could also either drop the quarter (effectively replacing it with with the 50 cent piece) or maybe drop the dime and have quarter, half dollar, dollar, and five dollar coins. After all, given how hard it is to get the coinage changed, you certainly want to get ahead of the game when you do it, and this would pretty much put our coinage in the situation it was in in 1857 when the penny first became our smallest coin.
However, I think that the best system that has any chance to be implemented in my lifetime would replace the six coins currently in common use (penny, nickel, dime, quarter, half dollar, dollar) with coins of denominations $0.10, $0.20, $0.50, $1.00, $2.00, and $5.00, taking us back roughly to the mid-1960s in terms of the value of our smallest coin. And the size of the coins should increase (slightly) as their value increases, avoiding the current situation in which we have a $0.10 coin (the dime) that is much smaller than our $0.05 coin (the nickel).
Need more convincing? It costs us 1.7 cents to make each penny. The cost of handling a penny in a transaction exceeds the value of the penny. Pennies, nickels, and one dollar bills are relics. Let's get rid of them. Our inability to fix this is equivalent to hanging a huge sign on the Statue of Liberty saying "America is on the decline and cannot do even the simplest thing to right her ship." Except that the sign would be far less expensive to maintain.
Finally, here is a great video rant on this topic. That is not me in the video, but I'm a lot like this when I think too much about the issue — it drives me completely around the bend.
UPDATE: There is a petition on the White House web site about this, and President obama actually responds here.
Also, impact is not a verb, except that my head might not ache to hear you say, e.g., "a meteor impacted the Earth" (though even that sounds slightly pretentious; what's wrong with "hit the Earth" or "struck the Earth"?). Similarly, you might say that the Earth was "impacted by a meteor," and you might have an "impacted tooth"; but otherwise you should stick with "A affected B" or "A had an impact (or an effect) on B." Who started this business of replacing the verb "affect" by the non-verb "impact" anyway? Is everyone trying to sound like Al Haig?
Like 7 to 10 percent of males, I'm red-green colorblind. This isn't really a gripe (although as a joke I used to gripe at my mom for passing the gene on to me), but it would be nice if people who make graphs and maps and other things that use color to carry information realized that many of us are missing the picture. There are sites and even programs to help, like this one.
By the way, if the background of your powerpoint slides is white, we probably can't see the dot produced by your laser pointer.

This isn't really a gripe either, but both the American (e.g., 2/27/2013) and the European (e.g., 27/2/2013) methods of writing numeric dates are terrible (especially if you ever have to sort data by date). XKCD explains how it should be done:
