I suppose it is possible that the sign is intended to read: “We do Mom’s hair and Dad’s hair too” — but given my experience of punctuation on Staten Island, I doubt it. The sign is the window of a barber shop specializing in childrens’ haircuts. To my son’s fury, they have seats shaped like cars, airplanes and fire trucks, but *not* like frogs.
