This might be the funniest video you'll watch all year long.

Spectators at the Bronx Zoo got the extra experience when they were visiting the gorilla exhibit when one of the gorillas gave the other a mouth hug about 3 feet from the glass.

It seems innocent enough, with one gorilla chilling on top of a rock, until he locked eyes with one of the other apes. They must've done this once or twice before, because he immediately hopped off of the rock and assumed the position.
