In 1987, the Palms Bar in town began sponsoring the "World's Shortest Saint Patrick's Day Parade." The parades, which are less than a block long, have been getting shorter each year as other towns compete for the title. One of the mainstays of events has been a garbage truck driving down the street at the beginning, pouring out buckets of green water as a Maryville homage to the dyeing of the Chicago River green. In 2015, the parade moved from being a block off the square to actually being on the square after it became sponsored by Burny's Sports Bar.
