"First they came for the Communists,
and I didn’t speak up,
because I wasn’t a Communist.
Then they came for the Jews,
and I didn’t speak up,
because I wasn’t a Jew.
Then they came for the Catholics,
and I didn’t speak up,
because I was a Protestant.
Then they came for me,
and by that time there was no one
left to speak up for me."

According to the fantastic YouTube channel Numberphile, you can make all of them. Really. You just have to have some fun and get creative.”
