John Oliver Shows Why Donald Trump's Wall Couldn't Possibly Work

“It’s a big, dumb thing that only gets more expensive over time."

The border wall proposed by Donald Drumpf... err... Trump isn't just an incredibly dumb idea.

It's an incredibly expensive dumb idea, according to John Oliver, who did the math and found that Trump's numbers just don't add up.

On HBO's "Last Week Tonight," Oliver found the true cost of building the wall would be around $25 billion -- between two and six times the wildly varying estimates given by the GOP frontrunner -- and that doesn't even include the cost of maintaining it.

“It’s a big, dumb thing that only gets more expensive over time," Oliver said. "It’s like getting a pet walrus. You think it’s stupid now, wait until you learn what a bucket of sea cucumbers costs. You've not prepared for that.”

So Oliver has a much better plan -- one that would save the country about a billion dollars over the cost of the wall and give every American something much more comforting.

Editor's note: Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims -- 1.6 billion members of an entire religion -- from entering the U.S.
