The Suggestion-Box Paradox Ok, I've been carrying this catch for quite a while, and a "friend" of mine tried to convince me that it is in fact not a paradox, and that I was "wrong" Anyway, Here's the catch. Let's imagine you have just recently started a new school year, and a suggestion-box for what that can be done better/differently is being created. There are two rules for this box, two rules that "cannot" exist if the other one does. The first rule is: If the box gets at least one suggestion, the class will continue with the suggestion box (if no one have a suggestion, it's no point in having it) The second rule is that whatever ends up in this box, the class have to agree on (remember, this is just theoretical) Ok, with these two rules in mind, what happens in the case where the box receives a suggestion where it stands "remove the suggestion-box"? So you know, this is #SelfInvented
