The Simpsons kick off its 27th season this Sunday Night @ 8 pm ET/PT, only on FOX, check your local listings.
Season 27 begins with Homer being diagnosed as a narcoleptic, which sends him on a bender, after which he returns home drunk. This prompts a visit to a marriage counselor and results in a trial separation from Marge, during which Homer finds himself a 20-something companion.
Entertainment Weekly got a first-look at this Sunday night’s all-new episode of The Simpsons featuring Lena Dunham as guest star and you can watch it here.
"There are also other characters that come and go (also owned by the Warner Bros. Discovery conglomerate media company)."
