I had a stealth dog come at me today. I didn't even know he was there until I looked in my rearview mirror. I yelled at him "get a job" all sarcastic like and he stopped running (thanks OakLeaf).
I think the insults work. Kinda like that old Will Ferrell skit on SNL where he's some doctor that says the best way to train your puppy is to be sarcastic and humiliate him. Ha!
