i do this all the time and have been doing it for years... whatever song is on turn it into a song about poop & pee, going to the bathroom, etc maintaining the rhythm and rhyming structure of the song... as you can imagine it's really easy... but it's like a little activity for myself and the perfect balance of using my brain and not using my brain at all because it's so dumb... it's too bad my song improv abilities are limited to poop/pee-centered lyricism
