Here's to Nog, the Slightly Bemused.
About 36,000 years ago -- more or less -- ol' Nog was out on a hunting trip, stumbled across an orphaned litter of those four-legged barky things and thought: "Huh. Wonder of the kids would like to play with a couple of these?"
... And things were Never The Same Again.
Hoist a pint to the memory of Nog -- who never knew that dropping a couple of puppies into his pockets for the kids would literally change the world -- and give any doggies in your cave a good belly-scritching.
