Check it, now paper make a plane & paper make it rain
Paper (money) can be used to fund and create massive works of technological achievement like aeroplanes that can be of great benefit to humanity or it can be used to fund mindless ignoble activities like making it rain on strippers.
Paper (money) can also make warplanes that can be used in war to rain down bombs on innocent civilians abroad. Also a double entendre for making a paper plane.
