Did you catch John Oliver on Last Week Tonight Sunday, or were you too busy watching the Oscars? If you had to skip, here’s what you missed: another forceful Donald Trump takedown, a well laid-out defense of Obamacare, a breakdown of why the G.O.P.’s plans to replace it sound a lot like a thong—and, at the very end, a return of the “Dog Supreme Court.”

As he opened the show, Oliver lamented, “We must begin again with President Trump—two words that continue to sound unnatural together, like ‘walrus porn’ or ’Tilda Swinton.’” The comedian reviewed Trump’s most recent actions on immigration reform—including his casual use of the term “military operation”—as well as his reversal of Obama-era protections for trans students. “It seems, one by one, Trump is delivering on his promise to ‘Make Entire Subsets of the American Citizenry Concerned About Their Safety and Well-Being Again,’“ Oliver said before noting that the bathroom obsession tends to stem from the unfounded notion that trans women pose a threat when allowed in women’s restrooms. In addition to the fact there’s no research to support that idea, Oliver noted a huge irony: Trump himself has himself both denied and bragged on tape about going backstage before the Miss Universe pageant, when “everyone’s getting dressed and ready and everything else,” adding that since he owned the show at the time, he could ”sort of get away with things like that.”

Then, it was time to address Obamacare—which the G.O.P. seems dead set on repealing, though it’s not so ready to replace that plan. Oliver offered viewers a simple breakdown of the four main tools the G.O.P. is considering, all of which have one thing in common: they don’t seem to cover everyone quite as well as one would hope. Which is where thongs come in.

In explaining refundable tax credits—one of the most precious weapons in Paul Ryan’s arsenal—Oliver noted that the tax credits currently being proposed are not sufficient to cover even the barest-bones plans on the market today: “A tax credit that small helps cover your health insurance the way a thong covers your dad’s ass: it doesn’t. And there’s something that’s fundamentally wrong about that.”

As for health savings accounts (H.S.A.s)—another popular G.O.P. suggestion? Same issue: “They’re great for rich people; they’re basically a tax shelter,” Oliver said. “But if you’re too poor to save, or you get sick enough to blow through what you’ve saved, you’re not going to be covered, and you have that thong problem again.”

And block grants—which would replace the current mandate for the federal government to fund a certain percentage of a state’s Medicaid needs, instead offering each state an arbitrary amount of funding? “If costs start to rise and the block grant doesn’t keep pace, guess what, it’s that thong. Thong thong, thong thong thong thong.”

In closing, Oliver chose to lighten the mood with some comic relief—returning to his “Dog Supreme Court” to address Neil Gorsuch’s nomination to the Supreme Court. Since Gorsuch—whose seat constitutionally belongs to Merrick Garland—is a historical aberration, Oliver chose to make his stand-in on the Dog Supreme Court a little unorthodox, too. Instead of a dog, he’ll be represented by one of three lobsters, “all of whom, like Neil Gorsuch himself, have absolutely no business being here.”

“So choose wisely, America, because this is a lifetime appointment,” Oliver concluded. “And lobsters can apparently live to be 100 years old. Who knew?!”
