Scavenger Hunt

A woman answered her front door and saw a little boy holding a list.
"Ma'am," he explained, "I'm on a scavenger hunt, and I still need three
grains of wheat, a pork-chop bone and a piece of used carbon paper so I
can earn a dollar."

"Wow," the woman replied. "Who sent you on such a challenging hunt?"

"My babysitter's boyfriend."
