In our forthcoming Think Like a Freak, the second chapter is called "The Three Hardest Words in the English Language."
I'm not going to tell you here what we argue are the three hardest words to say (although you can find out pretty easily by glancing at the Table of Contents). I want to know what you think are the three hardest words for people to say, especially in public. And by "hard," I am not talking about pronunciation, although I guess I'm not not talking about pronunciation either.
The best answer that is left in the comments -- as voted by a secret quorum of Freaks -- will win you a signed copy of Think Like a Freak or a new Think t-shirt, your choice.
