I remember back in the day Toys R Us had some promo going with the Saturday morning cartoons on like CBS or something, where during one of the commercials they'd air a "secret password" and if you went to Toys R Us that day and told it to them they'd give you some free prize.
My friend claimed that they gave him "Super Mario Bros. 6"; I got a pair of orange shoelaces.
