I don't know JAS well. However, if JAS had meant it any other way when he said "Mr. Smarty Pants", I highly doubt that he would have said "Mr. Smarty Pants".
Not that it will make one iota of difference, I want the mods to know that I believe that JAS is being treated unfairly. I've been frustrated with the atmosphere around here for a while now, and if I was fanning the flames carelessly, I would have been MUCH more outspoken than I was. I fanned them very CAREFULLY. I know the context in which you called him a butthead. And I have a pretty good feeling for the context in which he said "Mr. Smarty Pants".
