What do you mean you need it like you need a hole in your head? You already have holes in your head. Five, if we’re not counting the eyes, which have often seemed to me to be physical holes plugged with psychic black holes. Anyway, even if you mean to say, “Like I need ANOTHER hole in my head,” it doesn’t entirely make sense. As Tyson reminds us, countless people choke every year because we breathe, eat, speak and drink out of the same hole — something the dolphins, for instance, don’t have to worry about. So you actually could use another hole in your head. “Like I need my body to grow nostrils and a tongue in my rectum” — now THAT would make sense.
