To cheat at something, vehemently deny it, get caught, and still proclaim innocence.
Rafael Palmeiro, a potential Hall of Famer with all kinds of accomplishments to his name, got busted for using banned substances. But he still denies it.
``I have never used steroids. Period."
You just got busted for 'roids.
``I am here to make it very clear that I have never intentionally used steroids. Never. Ever. Period."
Well, how do you explain that you tested positive?
``As I look back, I don't have a specific answer to give. Unfortunately, I wasn't able to explain to the arbitrator how the banned substance entered my body."
Rafael pulled a Valkrie.
