Lucy the Slut is one of the puppets in the musical “Avenue Q,” and like the other puppet characters she’s frequently displayed in their advertising. But not in Colorado Springs, Colorado, where a billboard company refused to put up ads showing Lucy’s cleavage. An exec for the billboard company told the local paper, “If I have to explain it to my 4-year-old or my grandmother, we don’t put it up.” Hey four-year-old, it’s a puppet. Hey grandma, those are boobs. Problem solved.
