The Simpsons Sneak Peek: Glenn Close Returns for a Valentine's Day Haunting

Leave it to The Simpsons to blur the line between Valentine’s Day and Halloween.

Sunday’s very special episode (Fox, 8/7c) finds the residents of the Springfield Retirement Castle suffering from a drug-induced hallucination that causes them to relive their fondest memories — which, on V-Day, pretty much all revolve around lost loves.

Enter Mona Simpson (voiced once again by Academy Award nominee Glenn Close), who returns from beyond the grave Grampa’s memories in TVLine’s exclusive sneak peek to remind the ol’ coot of better days gone by.

It’s sweet… you know, in a hallucinogenic kind of way.
