The line comes from The Room, the 2003 independent drama written, directed by and starring Tommy Wiseau as Johnny. In a flower shop scene, Johnny barely notices the dog beside the register before greeting it and moving on to buy roses. As the film became a cult favorite through midnight screenings and clips shared online, that throwaway moment became one of its most quoted jokes. Its fame grew alongside other Wiseau lines, and the brief greeting remains popular because anyone instantly gets the awkward, affectionate tone.
