On Sunday night, John Oliver returned to Last Week Tonight and took on controversial radio talk show host and conspiracy theorist Alex Jones, but not for his conspiracy theories.

Oliver claimed that after viewing Jones’s program for a week, he spent nearly 25% of the time talking about or playing ads for his products, which include survival gear, supplements, and organic shampoo and body wash. He mocked the “Combat One” moist toilettes that specifically state that they “can be used anywhere needed, including the perineal area.”

“That’s right, Alex Jones is trying to sell you sloppy wet rags for your taint,” he exclaimed.

Oliver pointed out the Bill Clinton rape whistle that’s for sale on his website and in the description it reads, “Let Bill Know You’re in the crowd and that you know the truth.” He actually bought it for $6 and it came with a free “9-11 Was an Inside Job” bumper sticker.

He mentioned that two-thirds of Jones’s funding reportedly comes from his products.

The HBO host then went after Jones’s “medical expert” Dr. Edward Group III, who Jones insisted that he “got his degree from MIT.”

After doing some digging, Oliver confirmed Group has a chiropractic degree from Texas Chiropractic College. However, he has five schools listed on his LinkedIn page and he did not graduate from any of them. Group even confirmed to the show that he does not have an undergraduate degree and MIT told his program that “it is not accurate to say he has a degree from MIT.”

He also took a jab at Megyn Kelly when referring to her interview with Jones on her program, calling it “Rationalizing Low Ratings with Megyn Kelly.” Jones told Kelly that it costs $45-50 million to keep InfoWars running and that the money he’s making is going back into the show Oliver claims “looks like it was filmed on the set of a porn parody of itself.”

Oliver then slammed Jones for urging his viewers to “fund” his show through his products.

“It’s like an NPR pledge drive for people who hate NPR,” he quipped.

He noted that an ex-employee said of Jones that he “can sell 500 supplements in an hour…it’s like QVC for conspiracy.”
