From Muppet Wiki

Dear Abby is a syndicated newspaper advice column which debuted in 1956. Readers send in letters to "Abigail Van Buren" (pseudonym of Pauline Phillips until 1995, and then her daughter Jeanne Phillips), who provides counsel on relationship matters, ettiquette concerns, and other issues. The column was adapted as a radio series from 1963 until 1974.
