When you post the same picture virtually on every thread, it's no longer funny - it's suspicious - especially when a Federer fan does it totally out of the blue. The intention doesn't seem innocent anymore given the rivalry.
Yet you can't address the facts of the photo - Nadal grabbing another man's ass, so you deflect onto Federer fans.
He did it in public. Surely that gives you some perspective? It is funny but it is also very cute. But how posting it several times on several threads makes it funny is beyond me but then again, I am not a Federer fan.

One thing for sure, he/she wouldn't have posted it if it were Federer grabbing someone else's butt. I can bet million bucks on it. The irony of it all, really.
Look, I find the picture funny just the not the fact that it's been posted everywhere even on Murray's thread. That just begs the state of mind.
