Dog's Milk?
Reminded me of Red Dwarf:
Holly: "We ran out of milk yonks ago - we're on the emergency backup supplies now, Dog's Milk!"
Lister: "DOGS MILK!"
Holly: "Nothing wrong with dog's milk - full of goodness, full of vitamins, full of marrowbone jelly. Lasts longer than any type of milk, dog's milk."
Lister: "Why?"'
Holly: "No bugger'll drink it.......... plus the advantage of dog's milk is that when it goes off it tastes exactly the same as when it's fresh!"
