Crazy Dave is the eccentric neighbour from Plants vs Zombies, the tower-defence game released by PopCap in 2009, where he sells plants and guides the player between levels. His cheerful, unhinged greeting became shorthand for the game's humour, and clips of it spread through YouTube edits, gaming montages and meme soundboards as players revisited the original game. It remains popular because it instantly signals nostalgia for early casual gaming while still landing as a funny, out-of-place welcome in modern short videos.
