I have always imagined this song redone as a comedy. A clueless Seymour unsure of how to feed the plant.
-does it...HAVE to be human?
-then does it HAVE to be mine?
-well then gosh, just where do i go to get it?

And the rest flows into Audrey II telling him how and where. Ending with them seeing Audrey getting assaulted by her dentist boyfriend and it flowing into the standard of the song about him looking like a perfect example of plant food like we get.

Also in my mind, Seymour is portrayed by Jontron. Audrey II would sound like his bootleg Zazu from his bootleg episode featuring lion king games. The slow robotic tune a stark contrast to the usual Audrey II fast speaking tones.
