One day, an English professor was teaching his class about positive and negative statements, and how they vary from language to language…
“For example, in English, a double-negative, or even a triple-negative, though grammatically incorrect, is often used, and ends up meaning the negative.
“For example ‘I haven’t never seen nothing like that’ means, ‘I have never seen anything like that.’
“In some other languages, though, a double negative will, in fact, be interpreted as a positive.
“However, there is not a single language in which a two positives are interpreted to mean a negative.
To which a student in the back of class responded…
“Yeah, right.”
