¿Cada cuánto hay que echar a lavar un pijama? by Luis Piedrahita

There's this Spanish comedian called Luis Piedrahita who's rather famous in my country. For a few years he has been publishing his monologues in a total of three books with the title of one of the monologues. The first one was called:

• "¿Un cacahuete flotando en una piscina, sigue siendo un fruto seco?" [Can a peanut floating in a pool still be called a nut?] released in 2005.
• "¿Cada cuánto hay que echar a lavar un pijama?" [How often do you need to wash your PJs?] released in 2006
• "Dios hizo el mundo en siete días... y se nota" [God made the world in seven days... and you notice it] released in 2007
• "¿Por qué los mayores construyen siempre los columpios encima de un charco?" [Why do the older ones build the swing allways over a puddle] released in 2010. 

So far I have read the second and third, and I tell you, they are all hilarious. 

Luis Piedrahita was born in A Coruña [Galicia in the north of Spain] in 1977. He has worked in both radio and TV as writer, comedian and illusionist and was also director and writer of the mystery thriller 'La Habitación de Fermat'. He's known as the King of Small Things [El Rey de las cosas Pequeñitas], because he often critisices the little attention people pay towards the small things of cotidian life such as pockets, carnivorous plants, etc. 

I don't know if his books have been translated into other languages, but if you know spanish you should definitely check it out, because he's just too good. If you want to see him, you can find a lot of his monologues as well as his appearences in 'El Club de la Comedia' [The Comedy Club] and 'El Hormiguero'[The Anthill] on the Internet. 

And that's it.

Out of 10 I give his books a 9 and a 10 

The third one is funnier than the second one, but both are very worth your time.
