But nothing swept the social media platform like one man's plea for chicken nuggets. In April, Carter Wilkerson, a Nevada college student, posted a tweet asking Wendy's how many retweets it would take for the chain to offer him a year of free chicken nuggets. It went viral, making Twitter history as the most retweeted post ever, according to the tech company's year-end data, released this morning. (Bringing in 3.6 million retweets, Wilkerson came short of Wendy's answer: 18 million. But, rest assured, the student received his nuggets anyway.) These Were the Most-Liked Photos on Instagram of 2017 The next most-retweeted posts struck a more serious tone: Barack Obama's tweet featuring a Nelson Mandela quote came in second, followed by Penn State's post-hurricane pledge to donate $0.15 per retweet to Houston and Ariana Grande's heartfelt message following the terrorist bombing that occurred at the end of her concert in Manchester, England.
