"Lets not get too involved" joke

A pig and a chicken were walking by a church where a gala charity event was taking place. Getting caught up in the spirit, the pig suggested to the chicken that they each make a contribution.
"Great idea!" the chicken cried. "Why don't we offer them ham and eggs?"
"Not so fast," said the pig testily. "For you, that's a contribution. For me, it's a total commitment."
