This is when you know a thread's gone waaaay beyond any useful discussion. People forget what they've said, and then step in their own **** trying to be cute.

Here's a classic:

"Thank you for your input and calling question to ones intellect. Isn't everyone on this board a genius??? You apparently are. I am just a low down scumbag and my thoughts should not be heard right? Or is it that unless someone meets your specifications that they qualify in this debate?

Practice what you preach!! You may be old but definitely not wise!"

Then he responds to a comment that he doesn't like, but doesn't have an argument to, with a link to a page with this header:

"Welcome to the

Stupid People Pages!!!"

because he doesn't actually have anything to intelligent to say. Nice. You get all pissy and defensive when someone questions your intelligence, then you do the same thing to someone else, but with twice the malice and the subtlety of a 4x4 in the forehead.
