Partly Facetious: Political sponge or political animal?

"The silence of the lambs I say."
"That was a 1991 horror film and if I remember correctly it was about an FBI agent who seeks the advice of incarcerated Dr Hannibal Lecter, a brilliant psychiatrist and a cannibalistic serial killer, to catch another serial killer..."
"Details, details, what are you preparing for? A day in court? Let me inform all Nawalas daily denigrating the case put forth by the Pakistan Tehreek-e-Insaf in the Supreme Court that all roads do not lead to Panama hearings in the Supreme Court."
"I am sorry for so assuming but my statement was based on knowing that you are a political sponge..."
"The correct phrase is political animal."
"That maybe so for the likes of the Defenders of the Prime Minister and his three children's honour (DPMs) daily, cause they generate the goodwill of the Prime Minister and there is a prospect of directly benefiting from their spirited defence, but people like you sponge off the court proceedings and give your opinion without any benefit - stupid I say!"
"Ratings my friend..."
"OK, I get it but anyway what made you refer to the movie The Silence of the Lambs?"
"Well, you were right I was referring to the ongoing Panamagate proceedings but when I said lambs I was referring to lambs used in the biblical sense you know what John the Baptist says after he spies on Jesus Christ: Behold the Lamb of God who takes away the sin of the world."
"Hey, I don't know about that quote but Charles de Gaulle, the guy who liberated France and became President said: don't ask me who's influenced me. A lion is made up of the lambs he's digested and I've been reading all my life."
"A lion made up of the lambs he's digested! Note not ate but actually digested them...anyway can we easily insert tiger instead of lion..."
"Oh dear, you simply cannot resist being a political sponge. But my dear before you talk of digestion remember when your tiger was in Saudi Arabia..."
"I don't get it."
"Our politicians all suffer from serious digestive problems when not in power..."
"Don't be facetious."
