MICHEL: How about ‘The Money Pit’?
In American slang, a “money pit” is any property, possession or business which takes up an increasingly large amount of money to maintain it – usually more than was foreseen or budgeted for.
Michel is possibly referencing the 1986 comedy film The Money Pit, starring Tom Hanks and Shelley Long as a couple struggling to renovate their recently bought house. It closely parallels the 1948 Cary Grant comedy, Mr Blandings Builds His Dream House, and received lukewarm reviews. The movie does have a happy ending, a possible foreshadowing that Lorelai and Sookie will have one too.
