Why would you want to do such a thing. This "know it all" you mention is obviously a wise talented person - why would you want to upset him/her and break their confidence.

The problem here seems to be within yourself. Maybe you have jealousy issues or have struggled with your own education in the past making you resentful of this "Know it all"

Maybe you should look at improving your own knowledge by attending night school or listening more to this person, learning from them and maybe you will then start giving this person the well earned respect he/she deserves rather than looking at ways to hurt him/her.

Hope this helps.
