And nowe in the winter, when men kill the fat swine They get the bladder and blow it great and thin, With many beans and peason put within: It ratleth, soundeth, and shineth clere and fayre While it is throwen and caste up in the ayre, Each one contendeth and hath a great delite With foote and with hands the bladder for to smite; If it fall to grounde, they lifte it up agayne, But this waye to labour they count in no payne.

Medieval verse, one of the earliest descriptions of football in England.

I challenge all the men alive To say they e'er were gladder, Than boys all striving, Who should kick most wind out of the bladder.

  Charterhouse public school song, celebrating football.

My pappy told me never to bet my bladder against a brewery or get into an argument with people who buy ink by the barrel.
