I have mixed feelings about this joke, but maybe some of you will like it!

A farmer was passing a mental hospital with a load of fertilizer. A patient called to him through the fence, "What are you hauling?"

"Fertilizer," replied the farmer.

"What are you going to do with it?"

"Put it on my strawberries."

"And we put cream on ours--and people say we're crazy!" the patient responded.
