peacetrain , what do you want to say me by using this idiom as reply?

As you had only posted twice and each post was the same, I made an assumption that you aren´t here for the same reasons as most other people .  It happens sometimes.

Having googled your post, it seems you´ve been posting it on other sites too and, according to my web browser security, wikidioms doesn´t appear to be a secure site.  I thought at first that it may be a Wiki subsidiary, but I don´t think it is.

If I´m wrong then I apologise .

 Also on those "not so bright people" - I also use...

- Not the sharpest tool in the shed

- Not the brightest color in the crayon box

- Light´s are on, but no one is home

- Wheel is spinning, but the hamster died

- A few cards short of a full deck

- A few fries short of a Happy Meal

..... ok, maybe I use too many of these, too often (sorry, lots of dim people around here..)  Just tought  I´d share....

 - oops...BTW, speaking of dim - please excuse my typo´s!

useless = "as much use as a chocolate teapot"

Your references to the financial markets reminded me of some other ones:

Because we can never tell how well a business is doing - You don´t know who´s skinnydipping until the tide goes out!

About the banks: The sort of people who lend you an umbrella then ask for it back when it starts to rain.

Don´t forget ´a sandwich short of a picnic´

OOOPS-sorry-this was mentioned earlier on !!

someone who´s shy-wouldn´t say boo to a goose.

someone who´s talkative-can talk the hind leg off a donkey.

someone who´s big-headed-is too big for his boots.

someone not very strong-couldn´t knock the skin off a rice pudding.

Bir kulaktan giren diğerinden çıkmak - go in one ear and out the other

  wearing very formal or decorative clothes in a way that attracts attention

well that´s how I always understood it but, having looked at some other references, some use it for the opposite meaning . . . "to look a mess" or

"to make a dog´s dinner of something" = to make a mess of something.

Quoting peacetrain

 to kick the bucket = to die sorry to be so morbid

Tahtalı köye gitmek = To go to the wood village (i.e to die)

"Tahtalı köy" (wood village or village with woods) here means graveyard
