Warmest Wishes comes from Schitt's Creek, the Canadian sitcom created by Eugene Levy and Dan Levy, with Dan Levy playing David Rose, the fashionable and sharp-tongued son of the Rose family. The series ran from 2015 to 2020 and built a devoted following through streaming, where David's polished delivery and dry humour made many of his lines easy to quote and share. Fans began using this warm farewell in birthday posts, thank-you videos and fan edits, and its gentle sincerity keeps it useful long after the show ended.
