"Last Day on Earth" is the sixteenth and final episode of the sixth season of the post-apocalyptic horror television series The Walking Dead, which aired on AMC on April 3, 2016.

After Maggie suffers pain from pregnancy, Rick and the group urgently try to get her to the Hilltop Colony in their RV for medical attention; however, every one of the routes they take is blocked by a progressively larger number of Saviors, led by Simon (Steven Ogg), with increasingly frightening capabilities.

After nightfall, with time running out, Eugene volunteers to be bait to distract the Saviors by driving the empty RV by himself to lure them while the rest of the group carry Maggie to the Hilltop through the woods on foot.

In an intimidating manner, he approaches and greets a nervous Rick, revealing himself to be Negan (Jeffrey Dean Morgan), the totalitarian leader of the Saviors.

He introduces Rick to his bat, which he calls "Lucille", and reveals that the entire set up, including the roadblocks, was simply to decide "who gets the honor" of dying as punishment for their actions.

Unable to choose a victim, Negan claims to have an idea; he starts a game of "eeny, meeny, miny, moe", pointing Lucille down the line of survivors as he recites the rhyme.

[2] Director Greg Nicotero confirmed that they filmed two versions of Negan's introduction – one for broadcast with toned down language and the other for the Blu-ray release, which has swearing to match his speech from the comics.

The critics' consensus reads: Despite Jeffrey Dean Morgan's deliciously evil turn as Negan, the meandering "Last Day on Earth"—and its manipulative cliffhanger ending—make for a disappointing season finale.

[7] In response to the backlash the cliffhanger received, showrunner Scott M. Gimple said: If you approach it from a place of skepticism or with the idea that there's some kind of negative or cynical motivation behind it... it's difficult to convince you otherwise.
