A hen and a pig strolled down the avenue. The hen looked up at a huge billboard advertising ham and eggs.
"Look at those magnificent fried eggs with the orange yellow yolks," said the hen.
"Look at the fried ham steaks," said the pig.
They thought for a moment, then the pig spoke, "For you, those eggs were a contribution, but for me the ham was a total commitment."
Some make contributions, others are totally committed.
