Yeah, right

So, let me think this through. I've just signed a contract making me the world's highest paid athlete, and i'm going to let somebody (my cousin!) inject some stuff into me that i don't know what it is but he says it'll make me perform better, so i say OK?

I'm the world's highest paid athlete, remember? $25 mil a year for 10 years because of the stuff that my body can do, and i'm going to inject it with something that i don't even know what it is?

What a maroon.
