LOS ANGELES -- One of the longest lasting TV couples is separating.
Producers of "The Simpsons" say Homer and Marge will get a legal separation this fall.
The cause isn't homer's drinking; it's his newly discovered narcolepsy. Lena Dunham will guest star as the home-wrecking pharmacist who steals Homer's heart.
The next season premieres in September.
"Simpsons" producers also recently announced Bart Simpson archrival Sideshow Bob will kill his nemesis in a Halloween special.
