Cover art for Buzzards of Green Hill lyrics by Les Claypool's Fearless Flying Frog Brigade

Fuzzy Wuzzy is an old English nursery rhyme. Fuzzy Wuzzy was a bear Fuzzy Wuzzy had no hair Fuzzy Wuzzy wasn't fuzzy, was he? You can look up the historical significance of it on Wikipedia. I don't know what Les's intention was of adding it to the song though.
