So be sweet and kind to mother/
Now and then, have a chat!/
Buy her candy or some flowers or a brand-new hat/
But maybe you best let it go at that!/
Or you may find yourself with a quite complex/
... Com-plex!/
... and.../
You may end up like Oedipus/
I'd rather marry a duck-billed platypus!/
Than end up like poor Oedipus Rex!
"Oedipus Rex", final stanza. - An Evening (Wasted) With Tom Lehrer (1959)
