Quote by Welfare Agent (The Simpsons), The Simpsons

There are a lot of little tricks to it, things you should have learned a long time ago. Such as, if you leave milk out, it can go sour. Put it in the refrigerator, or, failing that, a cool wet sack. [later]...And put your garbage in a garbage can, people. I can't stress that enough. Don't just throw it out the window.
