Maximum Effort created a humorous three-minute infomercial for three Kraft Heinz coffee brands that stars Melissa Joan Hart from “Clarissa Explains It All” and is narrated by Nick Bakay, the voice of Salem the cat in “Sabrina the Teenage Witch,” in which Hart also starred. The ad contains nods to the shows, celebrates National Coffee Day and is running at full length during shows such as “Good Morning America,” “Bachelor in Paradise” and “Shark Tank.”
