All common sense should tell us that building a wall along the U.S.-Mexico border is an infinitely dumb idea. Unfortunately, some Americans—a baffling plurality of Republican voters—are in favor of such a wall, and want the man who proposed such an idea, Poorly Restored Fresco Donald Trump, to be president. And since Trump is the very likely Republican presidential nominee, we have to take his ideas—however idiotic, racist, and impossible—seriously. After ignoring the man through all of 2015, Oliver has made Trump his favorite target this season. In a crushing first hit, Oliver rebranded Donald Trump with his real last name of Drumpf. He even sold "Make Donald Drumpf Again" hats that were so successful Jay Z wanted one. Then, last night, Oliver dedicated his main segment to dismantling Trump's wall, point-by-point, brick-by-brick.

Putting aside the project's obvious xenophobia, Oliver started with the cost. Since announcing the idea last year, the cost of Trump's wall has been estimated as anywhere from $4 billion to $12 billion. Most rational people who aren't Donald Trump would find an $8 billion margin of error to be deeply troubling. But not if you're Trump, a man with the extra funds to throw at shitty steak companies, non-accredited universities, and magazines for rich tacky people. However, an actual estimate of building such a big, beautiful wall is closer to at least $25 billion, and will only get more expensive, as "maintenance costs will exceed the initial construction costs within seven years," Oliver pointed out.

"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, it's expensive as hell. And we're not paying for it, and Mexico has made it pretty, pretty clear that there's no way they're paying for "that fucking wall." But let's assume that America just magically got a huge inheritance from a wealthy parent and could pay for the wall. Where the hell would we put it? The U.S.-Mexico border is about 2,000 miles. As George W. Bush's Secure Fence Act demonstrated, it's kinda tricky even building a fence along a 700-mile stretch of the border. You have to build through people's property, build around geography, oh, and "waive 36 laws to build the fence, including the Endangered Species Act, the Safe Drinking Water Act, and the Native American Graves Protection and Repatriation Act," Oliver said.

Okay, so, assuming it's financially and physically possible to build this glorious wall, would the thing even work? Nope! "Nearly half of all the unauthorized migrants now living in the United States entered the country legally through a port of entry such as an airport or a border crossing point using visas they then overstayed. A wall can't stop that," Oliver said. "That's like wearing a condom to protect from head lice. You could do that. But that's not really how you keep the thing you're worried about from happening."

Here's a better idea that Oliver proposed last night: Instead of charging every single person in the country $77 for this dumbass wall, maybe just use that money to buy every man woman and child in America a Palmer Waffle Iron for $74.95.

"So come on, America!" Oliver concluded. "Let's ask ourselves what kind of country do we want to wake up to? One that spends billions on an impossible, impractical symbol of fear, or one that smells like breakfast? Exactly!"
