This one was passed around on Facebook as well, and while not exactly correct, was fun to read last week:
Steelers fans were nestled all snug in their beds,
while visions of first place danced in their heads.
The terrible towels were hung out to dry,
as they settled in for a first round bye.
When out of Candlestick there arose such a clatter,
... ... fans sprang from their beds to see what was the matter.
They saw that their dreams of first place just sank,
as they realized all roads come through M&T Bank!!
