Morty Smith is the anxious teenage grandson in Rick and Morty, the animated series that premiered on Adult Swim in 2013 and was voiced in early seasons by co-creator Justin Roiland. Short voice clips of Morty became popular on soundboards and in edits because his panicked, stuttering delivery turns even simple lines into a joke. This good job line spread as a reaction sound for low effort wins, ironic praise, and awkward encouragement, and it remains a staple in meme videos and group chats.
