Stupid thing to do regardless of what was said. If he really wanted to be a snide and do him he should have done it with a nasty challenge if he was going to do something since raising your arms is giving the opposition every chance possible to get you sent off without much resistance from the ref. Saying that though we should accept it was a snidey thing to do, accept whatever sanctions are imposed on Naismith and just carry on, nothing can be done about it now. It'd be nice if he could do it to suarez but a lot harder though, it'd be almost worth the red.
