I collect and maintain a list of examples like this. Usually stuff I see somewhere else or random ones that pop into my head.

My favorite simple one: "Unlike whiskey, you can't water water down."

My favorite long one: "I want to put a hyphen between the words Fish and And and And and Chips in my Fish-And-Chips sign"
