On Sunday's Last Week Tonight, John Oliver tackled the unexpected yet pertinent topic of kidney dialysis. And by the end of the segment, he helped launch a now-trending social media campaign, urging viewers to use the hashtag #WhenIDiePleaseTakeMyKidneys to indicate their support for organ donation.

Mentioning that chronic kidney disease was a leading cause of death in the U.S., Oliver claimed that the country spends "more, by some accounts than any other nation" on dialysis care, but the country has one of the "world's highest mortality rates," for it. The Daily Show alumnus looked at DaVita dialysis centers with CEO Kent Thiry at the helm. Oliver referred to Thiry as a "showboating musketeer," and said he takes inspiration from The Man in the Iron Mask starring Leonardo DiCaprio.

The clip featured a former DaVita patient expressing her concerns that she didn't receive the proper treatment because the clinic was running behind. In addition, an ex-nurse for the company alleged "it was all about numbers" and claimed employees were "not properly disinfecting" equipment in order to reduce turnover time.

At the close of his NSFW segment that runs more than 24 minutes, Oliver advised there are "key lessons" to be learned.

"First, we need to make sure that dialysis clinics have better oversight and we need to create better incentives for transplants and for treating kidney disease earlier to keep patients out of dialysis in the first place," he advised. "And there are things that everyone can do to combat the kidney shortage. Truly amazing people can donate one of their own kidneys while they're still alive."

"For the rest of us complete (expletives) we should at least, at the very least, be organ donors when we die," he added.
