I took out my wallet, extracted $10, and asked "if I give you this money, will you buy some beer with it instead of dinner?"
"No, I had to stop drinking years ago," the homeless man replied.
"Will you use it to go fishing instead of buying food?" I asked.
"No, I don't waste time fishing," the homeless man said.. "I need to spend all my time trying to stay alive."
"Will you spend this on hunting equipment?" I asked.
"Are you NUTS!" Replied the homeless man. "I haven't gone hunting in 20 years!"
"Well," I said, "I'm not going to give you money. Instead I'm going to take you home for a shower and a terrific dinner cooked by my wife."
The homeless man was astounded. "Won't your wife be furious with you for doing that?"
I replied, "Don't worry about that. It's important for her to see what a man looks like after he has given up drinking, fishing, and hunting."
