Dexter's Rude Removal refers to a legendary lost episode of the classic Cartoon Network series Dexter's Laboratory, which was produced in 1997 but remained unaired for years due to its profanity and crude humor. The episode features Dexter inventing a machine to remove the rudeness from himself and his sister Dee Dee, resulting in the creation of highly polite clones and foul-mouthed, chaotic counterparts. The meme typically uses stills of the rude clones to represent someone's unfiltered or aggressive side, or compares the two versions of the characters to highlight the difference between public behavior and private thoughts. It gained massive internet fame after Adult Swim finally released the segment online in 2013, quickly becoming a staple for expressing suppressed frustration or contrasting personalities.
