(The following is a conversation that took place this evening at the supper table)

Monkey: ~a made up song with the final line having to do with one being a big pile of poo~

The Music Man: I don't think we should talk about poo at the supper table.

Monkey: Well, poo is left-over food that your body doesn't need, and we talk about food at the table.
