Funny / The Money Pit

  • Walter reacts to the latest catastrophe by completely losing his mind and cackling like a madman for a good half a minute. Bonus points for Tom Hanks's belly laugh sounding a lot like a donkey. Shelley Long kept a straight face through this part (see it at the 2:20 mark), settling instead for a "Dude, Not Funny!" look, is beyond human comprehension.
    • Said catastrophe itself is worth a mention - after lugging buckets of hot water up an extension ladder to the second floor (due to the staircase completely collapsing), the two go to pour the buckets into the tub...only to have the tub fall through the floor and shatter below. Cue Walter's laughing fit.
