Crazy Dave first appeared in Plants vs. Zombies, the tower-defence game released by PopCap in 2009, as the eccentric neighbour who guides the player, sells plants from his car, and warns about incoming zombies. His frantic, rambling way of talking became one of the game's most recognisable quirks, and short clips of his voice have since been shared widely on soundboards, in gaming edits, and across meme videos. Fans still reuse them because the voice instantly evokes the original game while adding a burst of unpredictable, comic energy to almost any scene.
