Not so long ago, British stand up comedian, John Oliver did not hesitate even for a moment in declaring that he couldn’t give less of a sh*t about Donald Trump.

But that was way before Trump began winning multiple states and cruising on his way to securing the GoP’s Nomination.

This is when John Oliver decided to spend an entire show on the “Donald Drumpf” phenomenon.

Laughably so, Trump went on to win the SuperTuesday the very next day and termed Oliver’s show as “Plain, Boring and Irrelevant”.

As the fight between the foremeost comedians of Britain and America gets more and more intense, last night John Oliver spent 18 wonderful moments demolishing Donald Trump’s proposed wall.

Oliver showed Trump no mercy, covering everything from Trump’s absolute cluelessness about the actual cost of the wall and his plan (or the lack of it) to get Mexico to fund it.

“Yes, Donald Trump wants to build a wall on the U.S.-Mexican border,” Oliver said, “and based on his tone, he wants to (expletive) that wall.”

But Oliver didn’t just want to make jokes. He noted that the wall is “one of the few policy proposals Trump has talked about in detail,” and set about dissecting it ahead of Tuesday’s primary in Arizona, where the wall is a big issue and anti-Trump protesters have blocked roads.

“Instead of mocking it or dismissing it out of hand, tonight, let’s take a serious proposal by a serious presidential candidate seriously,” Oliver said.

Oliver began by noting the Trump’s varied estimates of how much his wall would cost: $4 billion, $6 billion, $7 billion, $10 billion and $12 billion. Estimating the cost of the wall based in part on a piece by Glenn Kessler of The Washington Post, Oliver concluded that the wall would actually cost “conservatively” $25 billion.
