Edible birthday cards are the latest novelty.
Post comes through letterbox. Young boy goes to look for birthday cards. Young child goes into living room to open post where his mother is sitting. Puts another card on sideboard. Young boy picks up another card and this one is edible. His mother opens it for her son. He sits and eats it (narration says candy cards are a boon to house proud women who don't like to clutter up the house with old cards).
