When the kids were still around one of mine was "I'm not touching you."
The ad pictured two siblings in the backseat of the car on a trip and as they like to annoy each other they got in trouble for making actual contact so it was hands off. They then resorted to getting as close as they could without actually making contact.
One I say around my husband is from the Progessive insurance lady, "Don't worry. It happens to me all the time."
