Soldier Ant 

Oh gawd this cracks me up. It's a dog defending a piece of meat against a Sony AIBO robot dog (with comical little tufts of hair stuck all over it.) Listen for the warning growls.. and the woman's scream at the end. It's timeless. (In fact, if you substitute a Frosty Paws treat for the cut of meat, and an actual small dog for the AIBO, we played out a very similar scenario with our two brats a couple weeks back.
