A butcher got along great with everyone in the
neighborhood except a mysterious swami. They hated each
other! One evening, the swami's pregnant wife had intense

his enemy's shop. "Give me a pound of liver," he said to the
butcher's clerk. The butcher whispered to the clerk from the
back of the shop, "Here's our chance to screw that no-good
bum." Pointing to the clerk's thumb, he said, "Weigh down
upon the swami's liver!"
