Kevin will take "any test, any time, anywhere," supervised by anyone in any reputable Quest diagnostic lab (or other reputable lab) and you can even stare at the cup as it's going in. he's natty natty natty, no doubt, and what's interesting is the psychological component of those who refuse to accept this fact.
Fill in the blank: if I were to accept this as fact, it would mean I'd have to (fill in blank.)
Doubters are afraid to (fill in blank) so they continue to doubt despite all evidence to the contrary. Stop bullshitting yourself and give props where they're due.
Why would someone offer to take any test if there was even a chance they could get called out and look stupid and ruin their credibility forever? If he turned down offers to get tested we would have heard about it by now. Maybe this is a wake up call to those of us (myself included) who have relied too much on the special sauce.
