Sans is the skeleton brother from the indie game Undertale, released in 2015, whose deadpan jokes and memorable encounters made him one of the game's most recognisable characters. Clips built around him spread widely through fan edits, gaming videos and meme soundboards, where a short voice moment can stand in for an entire joke. This calling version follows that pattern, giving creators a ready-made way to summon Sans without needing game footage. Its low-fi, fan-made feel is part of the appeal, keeping the humour informal and instantly familiar to Undertale fans.
