DiSC Personality Profile...

Hey my wife and I just took the DiSC personality profile last night. It's extremely interesting. Any of you guys done this before? I thought it might be sweet to see what kind of personality we all have according to one of those tests. Maybe we can find a really good free one (DiSC is $10) on the internet or something. The DiSC one is cool because it focuses on the personality in relation to environment and groups, but I doubt we can all drop ten bones for it, or that we would want to. I had to for a class (Leadership and Team building - Dave Smith). Let me know what you guys think.
