Then there is the Green Acres episode where they have the generator, Lisa burns it out, and Oliver tries to explain the "rule of seven", where the appliances have a number, and they cannot total more than 7.
Their chart is
Can Opener -- 1
Coffee Pot -- 2
Iron -------- 2
Toaster ----- 2
Mixer ------- 2
Frying Pan -- 2
Rotisserie -- 4
Dish Washer - 5
Washing Machine 6
Freezer ----- 6
Refrigerator 6
All horribly skewed (no way a household refrigerator, even back then, would use 3x the power of a coffee pot, which mine is 660W, or a can operner would draw 330 W)
