All kidding aside, calling out the anonymous getbigger in Musclemag isn't a good idea.
This means at the Arnold there will probably be 10 or 15 kids who will repeat the stunt. Then if he mentions it again, there will be 50 kids yelling it at the 2007 Mr O. Imagine the flustering if 20 people are changing "Two For----ty" as he poses at shows.
If the goal is to let it go, then mentioning it is a mistake. If the goal is to try to create *buzz*, well, winning a pro show might be a better way to do that. I've outgrown the lame online battling antics, I hope he can eventually do the same.
