cereal milk

After eating cereal that is full of sugar or chocolate, if you have milk left over, the milk will be very sugary or chocolatey. Some great cereals that do this are Fruity Pebbles, Cocoa Pebbles, Frosted Flakes. The ones with chocolate usually leave chocolate milk that is good, but not as good as real chocolate milk. The best is when you are at the end of the cereal box and all you have is powder, which dissolves straight into the milk.

Alternatively, and this is mostly for the college students who are lazy, lacking in hygiene, or both, in the house, milk, whose¹ expiration date has passed, but not by far, such that the smell and the color of the milk cause you to not really want to drink it outright, but masked by the taste of some children's cereal (Honey Smacks are good for this), it is reasonably palatable. Just don't tell your mom that you were drinking expired milk. She won't like that.

Oh, you want a concrete example?

Say it's October, Friday the Thirteenth², and the expiry date on your milk was for Wednesday. Now, you could throw the milk away... but it smells ... sort of safe - and besides, you're hungry! You want to eat some cereal NOW! Go for it; I promise it won't hurt. much.

¹"who's"? That's not the right posessive, at all! Can someone help me out, here? (addendum: "whose"! Thanks, deep thought)
²Hey! By Jove, it is Friday the 13th! How convenient!
