Lol! On topic. I think being "smart" is nothing more than having specific expertise, or even just being somewhat well verse, in one or more things. That doesn't mean that you cannot be a complete ignoramus otherwise. For example, to pinpoint a more broad aspect of being smart, some people are "street smart," but outside of that they are illiterate, computationally challenged, uneducated in history, etc. Others, like myself, struggle with "street smarts" but find their musings in the realms of philosophy, language, science, math, etc. and excel in all of them. We call them "book smart". They usually are good with concepts and paperwork, but when it comes to practical application, unless they work hard to make up for their lack of skills in the practical world, they will fail. You can also be smart with specific subjects. Some people, like mathematicians, are very analytical, and therefore they excel at math, but unless they can find some sort of logical way to understand language, they usually do not do as well, and when it comes to writing they are usually bland because of a lack of imagination. I think intelligence is more of a general smartness. Someone who is intelligent excels to some extent in each category, though may not be specifically brilliant in any one category. Knowledge, to me, is the collected information that comprises smartness and intelligence; the more knowledge one has, the more smart/intelligent he/she is. And it's not necessarily that one is smart OR intelligent. Smart can determine what someone is in a specific sense, ie: "he is a smart man when it comes to math" and intelligent would of course then be the braod sense, ie: "he is a smart man when it comes to all subjects, therefore, he is intelligent". Wisdom, to me, is the reflection of the collected knowledge, so therefore it is a more active word. Someone is wise when they act intelligently and reflect their knowledge either through words or actions. So basically, wisdom is the expression of knowledge, either through words or actions. By extension we could conclude that someone who is wise is able to find practical use for their intelligence; wisdom is, in fact, applied intelligence. Therefore, I would say that the ultimate goal in this respect is to become wise.
