why does chachi wear a bandana on his leg
Chachi Arcola After his initial appearance, the character of Chachi was expanded to a recurring character due to positive reception by fans, with Baio receiving up to 5,000 fan letters a week.[2] When the writers began developing the character of Chachi as a musician, Baio was against the idea because he "didn't sing," but changed his mind based on the possibility of the fame associated with becoming a pop singer.[2] His early catchphrase "Wah, wah, wah!" became popular with teenage girls.[2] However, an attempt to spark a fashion trend by having Chachi frequently costumed with a bandana tied around his pant leg did not catch on.[2]
