Whether it’s a darts player’s heartwarming tribute for Memorial Day or the NHL’s viral celebration of their championship win, some sports moments captivate the world and get the internet talking. These “viral” moments can be totally unplanned, like Freddie Andrews’ decision to slide down the metal divider between two London Underground escalators after watching the World Darts Championships, or they can be carefully engineered with the help of a creative agency such as Zoomph.

Regardless of how it is created, a good viral sports moment must satisfy three basic criteria:

1. Will You Talk About This in 25 Years?

The goal of any athlete is to reach the pinnacle of their sport and become an immortal legend. For some, however, that dream may be interrupted by a series of unfortunate events that leave fans scratching their heads. That was the case when French pole vaulter Anthony Ammirati’s manhood got in the way of his shot at Olympic glory.

2. Will You Share This?

Sharing a big sports moment on social media is one of the easiest ways to go viral. This year, the most popular shared sports moment was a slow motion soccer goal that garnered over 18 million impressions. Other big shares included a viral MLB video featuring Kevin Costner, Aaron Judge and lots of corn and a clip of NBA star Fred VanVleet verbally unleashing on a referee.
