GIF via Reddit (r/sports)
Real Madrid star Cristiano Ronaldo is one of the most athletic soccer players on the planet and his vertical leap is among the most impressive of his attributes. Because of that, it would only be natural for someone to set up a display that encourages people to humiliate themselves attempting to recreate a Ronaldo jump.
In this Cristiano Ronaldo display, there is a ball dangling from the ceiling for everyone to show off their vertical and attempt to get their head on it.
Of course, most people fail and it makes for an amazing GIF.
