Gibson was the home plate umpire for Game 6 of the National League Championship Series on October 18, 2013. At the start of the game, a "standoff" developed between Los Angeles Dodgers' first baseman Scott Van Slyke and St. Louis Cardinals' pitcher Joe Kelly. Both players remained on the field after the pregame ceremony, each waiting for the other to return to their respective dugout. Gibson ended the standoff by motioning both players back to their dugouts, with the Dodgers celebrating in their dugout after a Van Slyke victory. This incident was recorded in video form, and was used as an outro by the MLB's official YouTube channel for all videos posted in 2014. The outro has developed into an internet meme, and Gibson has become one of the more well-known umpires in the league thanks to this video clip.
