Han Solo memes encompass a wide range of iconic moments from the original Star Wars trilogy, most notably his cool-headed response 'I know' to Princess Leia's confession of love in The Empire Strikes Back. The character, portrayed by Harrison Ford, became an internet staple due to his rogue charm, the 'Han Shot First' controversy from the 1997 special edition, and his iconic shrug. These memes typically celebrate confidence, sarcasm, or the 'scruffy-looking nerf herder' aesthetic, making them a cornerstone of sci-fi internet culture for decades.
