Oldman,
Spelling was the excuse to justify the insult. If he had the ACM for the fight he wouldn't resort to "argumentum ad hominem" quipping to make him appear a literary genius and a hero of the silent masses in his audience with his drive-by. One liners are very rarely the work of a confident literarian. Most often someone playing the audience by insulting them with their own addiction to the baser conduct they whish they could use as the normative for personal conduct.
Anyone can pick up a "Horse Apple" and fling it to make themselves look good knowing it will always garner a laugh from the baser minded in the audience. The trick is to never let the audience smell their hand, so as to give a false impression of smelling like roses from previously splashing themselves with "Eau de toilette" as some form of moraly positive magic. Anyone with no self respect can fling a "Horse Apple". But, a fool only convinces fools his hand smells like a rose.
Hmmm first veracity or expertise. Now "Horse Apples", smelling like roses or being fools.
