Re: Shatner calls Abrams "A Pig."
I think Shatner was being sarcastic and joking in this.
Well, yeah - that's pretty much a given.
The press keeps inviting Shatner to comment on this or that, because they know he's nearly always willing to oblige with something funny or outrageous (or both.) They get something to print; Shatner gets an opportunity to ham it up; everybody's happy.
