If you don’t know what a Kong is, it’s a hollow rubber chew toy into which you place treats or kibble.  It’s constructed in such a way that it is difficult for the dog to get at the treats.  The first two times we used it, it took Homer about an hour to extract the biscuit.  I was about ready to nominate this thing for the greatest invention ever, but the little *** was smart enough to figure it out on the third try.

Looks like you’re still safe, sliced bread.
