A professional comedian resorting to "haha, she's bald jokes" and all the partner of the butt of the joke can think to do is to walk up and slap him. 50 year old men acting like children.
Is it too much to expect that people who are paid to think up funny stuff can come up with something a bit better? I mean it's not like it was an off the cuff response to a heckle from someone he doesn't know, which might be understandable, instead someone actually sat down thought about it before writing it down.
None of it excuses Smith's reaction, of course, which was equally pathetic. It's not like he doesn't have the opportunity to say what he thought about it at a later date, is it?
