After 20 years in the pop culture landscape - Mortal Kombat isn't exactly an unusual touchstone. Broad references to ninjas, special moves, and fatalities are so commonplace - we couldn't possibly report on them all. An unusually specific reference during a sketch on The Tonight Show with Jimmy Fallon has stood out from the pack. See if you can catch it:

Spoiler Alert: The Intense Staredown between absurdist mountain masters Fallon and Robert Downey Jr hits the sweet reference right around the 1:42 mark. Did you catch it? You may have missed it. It's not often you hear a shout out to "The Dragon King" Onaga!

It just so happens 2014 marks the 10th anniversary of Mortal Kombat: Deception! Released October 6, 2004: The game was the first full appearance of The Dragon King - a once immortal ruler of Outworld who was slain by Shao Kahn, and resurrected through the plot of the game's "Konquest" adventure mode.
