Meet Bot-ston, created by coder and professional glaciologist(!) Martin O'Leary.
"In June 2015 I had the Gaston song from Disney's Beauty and the Beast stuck in my head for about a week. To exorcise it, I made this bot, which generates random versions of the chorus."
Bot-ston finds rhymes to fit the schema of the song and just recently gained the ability to sing them (on-key!) in a text-to-speech synth voice.
It will not—absolutely not—help to get the chorus of "Gaston" out of your head. If anything, it will only lodge it there more firmly.
Bot-ston, you are positively primeval.
