After being away for 17-years, John Oliver is taking on the civic duty of making sure cicadas know everything they need to know when they are expected to return this summer.

With no new episode of his HBO show "Last Week Tonight" airing last Sunday, Oliver spent at least part of his free time producing a web exclusive where he alerted the bugs of many of the groundbreaking things that took place while they were away.

Oliver Shares Groundbreaking News Update

Making the cut was news of the Boston Red Sox winning a World Series, even though in Oliver's mind it only served to make their fans "more insufferable."

News of a "curly-haired kid from NSYNC now being one of the world's biggest stars" and talk of a certain member of Destiny's Child now reigning as "our queen" was also celebrated.

On the flip side, Oliver warned don't expect to eat carbohydrates or see "Cosby Show" reruns.

At one point, Oliver also shares, "Amazingly, we all just stopped paying for our music and porn -- and I think we've gotten away with it."

Oliver advised this batch of the underground cohabiting creatures they should enjoy their time while they can, warning based on how things turn out this November there may not still be a planet in another 17 years.

Oliver Warns Bugs About Trump

He then flashed a photo of Republican presidential front-runner Donald Trump, before sharing, "And I do not have time to explain that to you."

Trump recently won his home state of New York and soon after that the five states of Maryland, Delaware, Pennsylvania, Rhode Island and Connecticut to reestablish himself as the prohibitive favorite to bag the GOP nomination over Texas Sen. Ted Cruz and Ohio Gov. John Kasich.
