Users scroll through a live feed of cranky holiday Tweets from every corner of the world. They select a favorite and craft a response Haiku. After choosing a festive background, they preview it and send it off to the Humbug. Once submitted, the Haiku is instantly uploaded to the Tumblr gallery and a link to view it is sent to the Humbug via the Twitter handle, @Haikus4Humbugs. Participants from over 90 countries created Haikus. Some of them super sweet, others absolutely hilarious.
