I needed an extension of my visa to stay in Bolivia so I went to immigration. A guy from Holland was standing in front of me in the line. The immigration officer asked him, "¿Cuántos años tienes? [How old are you?]
The Dutchman replied, "Tengo 27 anos." 'Años' in Spanish is years but 'ano' is anus. He had said, "I have 27 anuses."
The immigration officer smiled and replied dryly, "Ah ¿sí? ¿Tantos tienes!? ¿Y en dónde los guardas? Sabes qué, no se lo voy a contar a nadie. No te preocupes." [Really? so many! And where do you keep them? You know what, I am not going to tell anyone. Don't worry!]
The Dutchman looked on in confusion.
Oh the beauty of learning a language!
