John Oliver Slams "Absolutely Insane" Brexit Campaign

"You would expect the Brexit camp to have some pretty solid arguments. Unfortunately, many of them are bullshit."

Ahead of Thursday's referendum to decide whether Britain will leave or stay in the European Union—a campaign commonly referred to as Brexit—John Oliver took to the latest "Last Week Tonight" to urge the people of the United Kingdom to vote to maintain its EU membership.

"The EU is not perfect: it's large, confounding, and relentlessly bureaucratic," Oliver said. "Think of it like Gerard Depardieu: it's an unwieldy European body that's a source of great bewilderment. But Britain leaving it would be a huge destabilizing decision, so you would expect the Brexit camp to have some pretty solid arguments. Unfortunately, many of them are bullshit."

Many international leaders, including President Barack Obama, have warned against Britain leaving. And as Oliver showcased with a series of disturbing clips, those on the other side tend to be anti-immigration—and sometimes downright racist.

To help make his case, Oliver delivered a brilliant, profanity-laced anthem in hopes it would convince the United Kingdom to vote "no" this Thursday.
