And you know it.   .....never profess what anyone else knows, moron! You speak for no one but you!

Well you're probably right, I can't prove you knew it.   But if you didn't you're more mentally challenged than even I thought.  Must be in the 1%.   Most third graders would know it. 

Prove it all, otherwise, azzhole! You want to dance? But you can't provide facts!

The old "prove it" and the old derogatory name.   I think this might be a new derogatory name, at least a new spelling.   That is sooo tiresome.

You don't recognize facts when you see them.

Exactly what is it you want me to prove?   "All" is pretty nonspecific.
