Interesting theory, and maybe possible if it hadn't been such a bad troll job. In his shoes, with those goals, the first thing I would do was claim that the tainted substance was actually a penis-reduction medication, because due to an oversized schlong, there were issues in balance, especially with capoeira moves.
It was all part of a long range plan to actually undergo penis reduction surgery. Since he is pushing 40, it's getting harder and harder to cut weight to 185, and it makes sense to lose the extra penis pounds that are non-functional in the Octagon.
I would also like to take this moment to let the committee know that I may be getting a testicle reduction surgery soon for the same reasons, and also having the brass content removed from my enormous nuts.
At this point, it would be time to pull out the blue bottle of tainted liquid, and also a red bottle, and ask the head of the committee which one he would choose to be entered into evidence. Whichever he chooses, I would then drink the other one immediately in front of them.
At some point, he surely could have worked into his testimony: "Sex is natural, sex is fun, sex is best when it's one on one."
And it would have been a good opportunity to present expert opinions on how marijuana is an athletic PED.
But instead, he just whimpered a little and said he took a boner medicine from a foreign country. He dropped the ball, as far as trolling goes.
