Episode 5F18
Written by Matt Selman
Directed by KIay Hall
Also starring: Pamela Hayden, Tress MacNeille, Maggie Roswell
Special guest voice: Marcia Wallace (as Ms Krabappel)

Premise: It is Marge and Homer's eleventh wedding anniversary but their plans to dine out at the Gilded Truffle are wrecked. Instead, they go away for a weekend and rediscover their primal urges work best under fear of being discovered. They then embark on a series of escapades to almost get caught 'doing it'. Bart and Lisa meanwhile find a new version of the ending of Casablanca to show Grampa.

Features: Carl, Lenny, Moe, Grampa, Chief Wiggum, Mrs Wiggum, Agnes Skinner, Skinner, Milhouse, Ralph, Rev. Lovejoy, Helen Lovejoy, the Flanders, Gil, Sideshow Mel.

Couch: The Simpsons are frogs, with Maggie as a tadpole.

Trivia:

• The restaurant the Simpsons end up at is Up, Up and Buffet!, a themed restaurant constructed inside an old aircraft.
• Grampa won the Iron Cross during the war.
• As well as the version of Casablanca (Michael Curtiz, 1942), the old Jewish Guy in the Springfield Retirement Castle - who used to be a film executive - has a rare copy of It's A Wonderful Life (Frank Capra, 1946) with a 'killing-spree ending'.
• And Gil's used car-lot has the slogan Our Prices are Sky High!
• The song played over the end credits is Rock the Casbah, the 1982 hit by The Clash.

Homage: May not be deliberate, but the sequences where Homer's 'bits' are conveniently covered up seem very similar to those in Austin Powers: International Man of Mystery (Jay Roach, 1997).

Look out for: Homer calling his new fridge Cold Faithful, and the dog's reaction to his underwear. We also love Bart's asking whether something is priceless 'like a mother's love or the good kind of priceless?'

Notes: A superb episode which actually makes Marge and Homer's love life seem very real; everyone needs a bit of spice now and again, and they find theirs. The balloon trip is hysterical, and the attempts to explain their behaviour to a very worldly-wise Bart and Lisa are magnificent.
