A love-sick dog.
But every bone he digs up was put there by some other dog.
They all taste like other dogs.

But he stops.
"*******, the bones don't taste like other dogs,
My TONGUE tastes like other dogs."
"Those *******."

And so he spent the next couple months applying acid to his tongue,
To burn out the taste and smell of the girl-dogs he had been with.
But it never worked.

He's still trying though.
To burn the taste away.

He wants a clean bone.
