Bubble gum rapper (Bubble Gum Weekend)

Because the mere existence of bubble gum makes you tumble onto the floor in laughter, this is yet another Bubble Gum Weekend - in which we usually profile hilarious old gum commercials.

Care-Free put out a strange ad in 1992 for its bubble gum (a product nobody seemed to buy).

In this preposterous commersh, a stick of this massively unpopular brand of gum magically turns an opera singer into a hip rapper:

The ad is somewhat whimsical, though not quite as clever as earlier gum advertising promenades. But the fact that it shows a person repeatedly bubbling is considered by advertising experts to be the commercial's saving grace.

Trendy doesn't always mean more appealing. Even some viewers who cracked a smile at this ad probably still longed for the days of the goofy charm and simplicity of Care-Free's '70s ad campaign that featured historical figures like George Washington and the Wright brothers.

Now the '70s were some carefree times!
