Good additions, Q.

I sold my mouse, and I bought me a wife,
She cut my throat with an old rusty knife.

The good Rev, B-G was good at finding this kind of thing (although some suspiciously.) But I think a singer may think this possible ending is the very reason to Remember that a pussy cat is better than a wife.

It also confirms that children's songs, historically, were interesting and fun. These past 50 years of forcing dull, innocuous songs on children is likely the reason children don't sing anymore. Except sexy pop music.
