Phineas and Ferb premiered on Disney Channel in 2007, created by Dan Povenmire and Jeff Marsh, and followed the stepbrothers through 104 days of summer vacation. Its fast jokes, original songs and running gags made short audio moments highly shareable as the series spread through reruns, streaming and fan edits online. Clips linked to the show now circulate on soundboards as instant nostalgia cues, especially for viewers who associate the series with childhood summers, inventive builds and Perry the Platypus subplots.
