Our neighbor's dog got out and was leading him a merry chase. I came up to her and caught her eye, then looked over at their gate. She gave me a happy "You got me, pal" look and trotted right over to it.
Like most of my moments of perfect mastery, I've managed to avoid watering it down by trying it too often. The other time I tried, it didn't work, but that can be attributed to the fact it would have meant the dog crossing an invisible fence (she got across it and out of her domain in the heat of seeing a deer in our yard, then couldn't go back home until her owner came over and took the collar off).
