Sherry is walking through the zoo when she notices Bill throwing $10 bills in the monkey cage.
Curious, she walks closer and asks, “Bill, what are you doing?
Why are you giving the monkeys money?”
“The sign by the gate says it was okay,” he replies.
Sherry looks at him quizzically, “It did?”
“Yes, it said, ‘Do not feed.
$10 fine.'”
