"I Have the High Ground" is a catchphrase based on a line said by Obi-Wan Kenobi in the 2005 film Star Wars: Episode III -- Revenge of the Sith . Online, the phrase is often used in Prequel Memes, i.e. jokes regarding Star Wars: Episodes I, II and III.
"I have the high ground" is a line from the 2005 film Star Wars: Episode III -- Revenge of the Sith. During the film's climax, in which the characters Obi-Wan Kenobi (Ewan McGregor) and Anakin Skywalker (Hayden Christensen) duel on the fire planet Mustafar, Obi-Wan leaps over Anakin's head and onto a nearby hill. There he yells, "It's over, Anakin. I have the high ground."
The line has become a fan favorite inspiring memes, jokes, and other media. One of the earliest iterations comes by way of a Lego-themed webcomic on the website Irregular Webcomic, published February 24th, 2006 (shown below).
On May 26th, 2016, the stop-motion animated television series Robot Chicken parodied the "high ground" scene by having the the character Obi-Wan refer to his ownership of the high ground to justify his morally questionable behavior. Within one year, the clip has more than 2 million views on YouTube.
