There was a big to-do in Spanish-language radio on Friday, say LARadio.com and La Opinión (in Spanish but free). "El Cucuy," the afternoon DJ on KCSA whose billboards are all over town, apparently cursed Univision chairman Jerrold Perenchio at length on the air then walked out leaving dead air. La Opinión reported on Saturday that the DJ, whose name is Renán Almendárez Coello, was upset over the way Univision treated him.
