You have to drop whatever you're doing and read TB's links.
Superficially, it sounds like a knee-jerk reaction, like "Oh Yeah, who sez?", or "What's it to ya?"
But it gives him time to do more research, and forces you to come up with an answer to his link, and you are sidetracked from the point you are trying to make into some side issue that may not even be relevant.
And maybe you'll just say "its not worth the hassle" and give up.
