Back in the early 90's, when we used to have the national news on TV during dinner, there was a little blurb to the effect of "Scientists recommend selenium in your diet." My dad, wanting something sweet after dinner, was quick with "you know what's got seleium? Butterfingers." And then he got up and grabbed a mini Butterfingers candy bar that we had stashed in the pantry. So after that, the running joke was "I need some selenium" as justification for having that particular sugary treat.
