pig in a poke is the last play of the george clooney movie.. he
snuck into the other team for the last play of the final game...
hes the pig in the poke.
Close, if you recall, that was the Sergeant York. The "pig" is
the football; it's also called a "pigskin". A "poke" is a bag. When
you are buying a "pig in a poke" you're buying something unseen,
"hidden". Before the rules of football were developed, players
would hide the ball under their shirt, well at least try to do it
unseen by the opponent. The "pig in a poke" play was hiding the
pigskin under your shirt and running in a direction opposite where
the play action was directed.
