Not really "whacky" - but things I've done or do
Buy a chicken w/ gizzards inside - save up the livers in the freezer for chopped liver at a later date.
If a chicken or duck comes with feet & heads - save for soup or porridge. Same with fish heads.
Left-over rice = rice porridge for breakfast & fried rice for lunch the next day
Don't pour dressing on entire lettuce salad - let individuals dress their own portions. That way any left-over lettuce keeps better overnight to be used the next day.
Go to the market late in the day/evening when the vendors are ready to go home - often you can get good bargains, although the produce might not be as pretty.
If buying from an owner-proprietor, try bargaining. Can you get something cheaper if you buy in bulk? Can you get a discount for cash?
Making your own yoghurt is cheaper than buying, especially if you use powdered milk instead of fresh.
Save bacon grease for gravy base when you want gravy but don't have other drippings. It's also nice *for a treat* to use it to grease a pan for fried eggs or scrambled eggs.
If someone you know smokes tobacco - the un-smoked tobacco shreds of a cigarette butt can be used as part of a pesticide. Soak the tobacco in warm water for a day (~1 part tobacco to 16 parts water) until light brown & add some dishwashing soap. Spray it on your plants.
Another good home-made not too poisonous pesticide - 1/8 castile soap, 1/4 rubbing alcohol, 5/8 water. Especially good against spider mites and scale.
