"It is one big lie," said Armstrong. "I never failed a test. Not a single test. I am going to take Lance Armstrong for everything he has for spreading these lies about me."
Armstrong's lead attorney, Tim Herman, said: "I'm confused. But per Lance's orders, I will proceed quickly and fiercely with this lawsuit. Unless, you know, Lance Armstrong tells me to stop. The other one. Again. I'm confused."
Others close to the cyclist wonder if nearly 15 years of heavy and non-stop drug use has left Armstrong with cognitive issues or even dementia, as it's not possible to sue one's self.
Armstrong said he is of sound mind.
"You know who isn't going to be of sound mind? Lance Armstrong when he finds out I'm coming after him for spouting filth about me."
The cyclist says he believes Armstrong is worth nearly $100 million and he plans to get every cent.
"This time next year I will be worth $200 million dollars," he said. "And if Lance keeps saying these things, I'll sue him again and be worth $400 million."
