Metaphors for 'stupid'

[Sancho Panther]

A couple more English ones:-

The light is on, but there's no-one in.
A couple of bricks short of a load.
The lift doesn't go upto the top floor.
Thick as two short planks.

I also know a Spanish one, but as it's muy, muy feo I'm not placing it on this topic as I fear I may be banned!

I did tell it to my Spanish-born wife who laughed a carcajadas, then told me told me what she'd do to me if were ever to repeat it; it is that rude!

[aleCcowaN]

También me había olvidado de "caído del catre" o "caído del árbol, de la higuera, del techo, del naranjo, etc.".

Es nuestro (Forrest Gump) residente. [() = replace accordingly to your locale]
Es un idiot savant pero sin lo savant.
(Corky) lo asesora.

O el de Mafalda:

Susanita: -Comencemos el cuento echando a volar nuestra imaginación ... (lo mira a Manolito) ... claro, los que tengamos plafond"

"He/she was born yesterday" works very well, referring to extreme lack of common sense.

By the way, I came across a spanish reply to how to address somebody who sizes you up as "Born yesterday": "De que me viste la cara"

Is this typical usage in Latin America?

[AngelicaDeAlquezar]

"¿De qué me viste la cara?" / "¿Me quieres ver la cara?" can be used when you perceive someone is trying to fool you.

"No nací ayer" means one is not so naive as to let oneself be fooled.

Here is very common: "No llega" or "No da más de sí".

In Catalan: "No hi és tot" (no está todo, no está entero).

[poli]

dim
dim witted
thick
thick as a brick
sharp as a button
obtuse

[Sancho Panther]

British proverb "Not so green, as he's cabbage-headed!".

No, I'm not 100% sure what it means, either!

Perhaps another, more sagacious brit would be so kind as to explain it to me; my parents employed often fifty-odd years ago!

I'm still waiting for the green light for my very funny (but extemely rude) Spanish one!

Ain't no way I'm posting it without a guarantee of immunity, no sirree!

But that was the whole point of my starting the thread!!

You could post it and use the 'hide' function, where a reader has to click on it before it is visible. That it allowed (I think )
