Fair enough.

I have an uncle who's dad used to take him hunting for rabbit. They would invariably come across cow patties in the field where they hunted. One day his dad saw him whacking some of the partially dried-up patties with his walking stick. He told him to put his face down close to a freshly opened patty and tell him what he found. "It stinks don't it?"

That's what happens when you knock the tops off.
