yeah apparently if you have puffy cheeks you're a doper, but also if you are as thin as a rake then you're also doping.
So when you take the dope that causes puffy cheeks and combine it with the dope that helps you lose weight, the effects cancel each other out and thus if you appear normal looking on the "looks like quacks like" anti-doping test, you are a doper.
Since all cyclists are either thin, or normal looking, or have puffy cheeks this means that everyone is still doping and nothing has changed.  And since Lance never tested positive you can't actually catch anyone with the test, therefore, it's sole purpose is to promote interweb mass debate.
