Partly Facetious: It's like amoeba - merge, split and merge again

"Do you know which is the mother of all political parties in this country of ours?"
"Has to be the PML. But I wouldn't call it the mother of all parties, I would call it the only hermaphrodite party in our country."
"Hermaphrodite?"
"Yes, absolutely."
"How so?"
"Well, it just splits up like an amoeba and then may merge to split again...didn't know any mother could do that so often anyway."
"As in amoebic dysentery?"
"Well, an amoeba doesn't always cause dysentery like the PML doesn't always cause the runs if you know what I mean."
"Well, some always run and some stay."
"Yes but the PML always solidifies around the seat of power."
"So if you don't know where power is you merely have to see where the three stooges are going in a hurry."
"Which three stooges?"
"Did I say three stooges? Sorry, I meant the three musketeers, you know one for all and all for one."
"So who are they?"
"Chaudhary Jaat, Leghari and Jamali."
"Why is Jamali the last one you named? I mean considering he is the Prime Minister."
"You have to know where the nucleus of the amoeba is?"
"And that's with Chaudhary Jaat? But you know you are wrong. The nucleus is somewhere else, not in the PML."
"Well, true - the nucleus has been with the PML only once."
"Mian Sahib?"
"To be more specific Mian Sahib term number 2."
"Maybe they should give serving and retired COAS honorary membership."
"Ah yes, but why would they give it to a retired COAS - nothing the nucleus can attach to there to regenerate itself."
"Ah yes. Sorry about that."
