Tips from the Trenches: A Guide to Practical Parenting

In cases where you are forced to throw toys in the inside trash because of inclement weather or similar, be sure to "top off" the trash can with a gooey, slimey mix of last night's dinner leftovers, used teabags or coffee filters, and perhaps something like jello, rotten bananas (unpeeled), or gravy. This will help repel the efforts of even the most ardent of resident dumpster divers.

You may also want to break any unbroken toys destined for the dumpster. This will give you additional argument for elimintating the toy should it be found. In some cases, just letting a younger sibling play with the toy will make it useless enough for the trash.
