Now this is a perfect marriage between ‘Tonight Show’ guest and ‘Tonight Show’ game. On last night’s show, host Jimmy Fallon and guest Charlie Day broke into a quick game of 5-Second Summaries in an attempt to stretch their brains to the very boundary of "no, this is not enough information to accurately guess something."

The duo were tasked with playing a modified version of charades, expected to describe various movie titles with increasing time and information constrictions (i.e. you can’t say any word in the title or name any of its stars). Day, who is good at screaming, and Fallon, who is good at laughing, are terrible at this game. But that’s fun! Especially when Fallon crafts kind of the perfect two-word description for a famous movie, leaving Day utterly flummoxed.
