Partly Facetious: Difference between cow and water buffalo

"I saw three cows."
"Where?"
"Near the Prime Minister's Secretariat."
"Are you sure they were cows and not water buffaloes?"
"Hey, you say potaaato and I say potato."
"Excuse me, but there are two separate animals. I mean mixing the two up is like...like Rehman Malik saying on the phone he is eating an apple while he is really eating a banana."
"So crown me Rehman Malik?"
"These days that crown belongs to Afridi - a rather hirsute man, and that too by choice, but boy does he talk a dime a dozen with religious sentiments thrown in galore. I mean when you are trying to end a sit in..."
"Medina is where The Khan is drawing his inspiration from these days but isn't their kingship there."
"Don't be silly, anyway talking of cows..."
"You mean buffaloes..."
"Let's compromise how about W C Buffaloes?"
"What?"
"Water Cow Buffaloes."
"You aren't giving up, are you!?"
"Well, these WC Buffaloes that I saw made me concerned - I mean would the Prime Minister resell them though they did not belong to the PM House but were loitering..."
"Where did these animals come from? I mean it's not as if they have a homing device like cats have, you know they return to the house and..."
"Maybe The Khan got someone to jinx them to return so he can sell them again and fill up the treasury and..."
"You mean considering Asad Umar's contention that he would raise over 90 billion rupees through technical means hasn't panned out The Khan has taken matters into his own hands?"
"Hey, revenue has to be increased and what better way than to get the WCBs to return home to roost."
"I thought it was chickens who came home to roost!"
"I heard the chickens are penned in, while the WCBs roam free."
"Oh dear."
