Below is one of my favourite jokes. Beneath it is a translation in to Spanish – which I think sounds even funnier!
---
A dog walks in to a construction site and says "I'd like a job, please".
The foreman thinks for a moment. "Well, we don't really employ dogs, have you tried the circus?"
The dog replies, "What would the circus want with a plumber?"

Un perro camina en la construcción de un sitio y dice "Me gustarÃÂa un puesto de trabajo, por favor".
El capataz piensa por un momento. "Bueno, realmente no lo emplean perros, ¿ha intentado el circo?"
El perro responde: "¿Qué quiere el circo con un plomero?"
