Christmas is coming, the geese are getting fat
Please to put a penny in the old man's hat;
If you haven't got a penny, a ha'penny will do,
If you haven't got a ha'penny then God bless you!

Christmas is coming?   The very phrase is offensive to Jews, Muslims, atheists, agnostics, and others.   The geese are getting fat?   That's because evil corporations are over-feeding livestock housed in cages.   Put a penny in the old man's hat?   That promotes age bias.   And it's time to repeal Bush's tax breaks.   God?   Come on now!

So what are we left with for this rhyme?

The winter solstice is approaching, organically grown food is ripe for harvest
Repeal the tax breaks for the rich, increase minimum wages
If you can't pay your taxes, we'll put you in jail
If you don't pay taxes, may you evolve favorably

By the way, modern poetry doesn't rhyme.
