An imaginary person (let's call him Craig) hears of a new, very inexpensive Spanish language school in Quito.
He knocks on the door of the school and asks the woman, "Is this the new language school?"
The woman answers, "If, if! Between, between!"

*In Spanish, the word si can mean "yes" or "if," and entre can mean "come in" or "between."

Ok, so maybe three days in the rainforest warped our senses of humor.
