The link below will take you to the show "Special Delivery", which aired on THE ALFRED HITCHCOCK SHOW in 1959. The show was directed by Norman Lloyd. Ray Bradbury wrote the script, based on his very creepy short story, "Boys! Raise Giant Mushrooms in Your Cellar!" (aka "Come into My Cellar") And I hope no one happens to be eating a mushroom pizza while they're watching this show...
