What are some Spanish-language puns?

Question

I'm a beginner at Spanish and I was wondering if anyone knew some simple puns, similar to English-language jokes such as:

-Why did the boy eat his homework? Because the teacher said it was a piece of cake.

-There was once a cross-eyed teacher who couldn't control his pupils.

It doesn't have to be very funny, as long as you explain the joke

Answer 1

AntoineFranc inspired me to tell another one. Note: "Bellavista" (beautiful view) is a neighbourhood of my city:

¿Cuál es el colmo de un ciego? Llamarse Casimiro y vivir en Bellavista en un noveno be (9º B).

I'll leave the translation as an exercise for those learning Spanish.

Answer 2

I think you're asking for "colmos", e.g.

¿Cuál es el colmo de un sordo? ¡Que al morir le dediquen un minuto de silencio!

I'll try to translate that: What's the worst thing that could happened to a dumb? That everybody helds a minute's silence when he's dead!

Hehe, I didn't know that one! - lazarus1907, Jan 1, 2011
