There is a new commercial that features a singing fish. The annoying jingle has been stuck in my head for several hours and in addition to promising never to visit the fast food restaurant that sponsored the ad it brought to mind another annoying "fish."
A few years ago, the Big Mouth Billy Bass fad swept through the country and many people I know, smart people by the way, bought them and actually hung them on the walls of their homes and cabins.
By now I'm sure they are all gone, but to where. Apparently e-bay, because they have 26 of them for sale right now. And in case you have forgotten them, here is a short sample of one version (there were several).
