WATCH: John Oliver Dismantles Donald Trump’s Wall

As if his notoriously small hands, callousness, racist undertones (and overtones), and general unpleasantness weren't enough reasons to dislike and completely disregard Donald Trump as a presidential candidate, there's the looming threat of his wall along the US-Mexican border.

It's just business as usual for John Oliver on his latest episode of Last Week Tonight where he's collected information from experts refuting Trump's claims of cost and efficacy from multiple directions and put it all together in a blistering segment. Lumped together, all of Oliver's points further prove how unfit for presidency Trump is by illustrating how little he really knows about international relations, how things get funded on a national level, and how politics work at their basest forms. What a gem of an election cycle this has turned out to be.
