How to deal with a Know-It-All

You know the type. Always butting in with unwanted "help". 

You also find quite a few here on EP. Spewing forth their opinions as gospel. It might not be so bad if they knew what they were talking about, but the purpose of their comments isn't to actually help anyone. They're there mainly to brag about themselves while putting others down. They mention how smart they are, or how fit they are, or how sexy they are, or whatever.

If you dare disagree with a know-it-all, be prepared for the worst. But sometimes it can be fun. Once in a while I enjoy yanking the chain of a know-it-all just to see them vent.
