A couple of years ago a friend of mine and I came up with what we called "The Eugene Levy Rule" as a way to determine which catch-phrases should never be said by anyone...ever. Its simple. If you can see Eugene Levy (as Father in American Pie, but he's a similar character in other films), saying something in one of his "I can be hip too" moments, then we should probably stop saying it. I offer "mad props" as an example of this. More obvious examples include "Off the hook" and "Gettin Jiggy with it".
