Firstly, read the whole sentence.
Permissible undefined behaviour ranges from ignoring the situation
completely with unpredictable results
ignoring the situation completely with unpredictable results
ignoring the situation completely
ignoring the situation ...

Also: the standard says the results should be a characteristic of the
environment. If flying monkies is a characteristic of your nose, I
still say you have a strange nose.
