Our dog, the language genius

So, Luke knows the word "Starbucks" now. Every now and again, John and I go to Starbucks at night and lately we've taken to loading up the dog and taking him with us. He loves to hang his head out the back window and sniff the night air. We started out by saying, "Do you want to go to Starbucks?" and he'd give us this totally confused look, but then once he was in the car he seemed to forget having been confused just moments earlier. Now, when we say, "Do you want to go to Starbucks?" or even just "Starbucks?" he starts wagging his tail furiously and he bounds for the front door. We're way past fetching the paper at this point, I'm thinking about starting him on Latin language tapes.
