Its pretty basic American humor. I'll break down the impression its supposed to create:
"Your opinions, sir," Its a title, awe he's giving me a title
"are a large pile of fecal matter" hey that's mean, he's insulting me, that prick!
Overall it means, "hey that prick just gave me a title then insulted me and told me I was undeserving of my title. That son of a bitch!" Its called ironic comedy. Watch our TV shows. Its pretty much all we ever think is funny.
