Saltine

 So a saltine fell on the floor, and instead of throwing it away I threw it in the front yard near the bird feeders.  I figured that either a bird would eat it, or a squirrel, or if they didn't move fast enough then the ants.

Nope.

It's been in the yard for two weeks now, and nobody wants it.  It's gradually falling apart thanks to the sun and the dew, but there's not an animal alive that's willing to eat it.

It almost makes you feel sorry for it.
