Has anyone ever discussed a "FlyBy" here?

That is what we call it when out of the blue Ripley goes racing by at top speed - just like a jet will do at an air show. He never keeps running, he just races through whatever room we are in. When he was younger he used to grace us with at least one flyby every night. He would usually wait to do it until we were really into a good tv show or movie. It always makes me laugh but they are few and far apart these days.
