Ask a stupid question...

II was standing in line at a Wal-Mart with a large bag of Purina Dog Chow, and the woman behind me asked, "Do you have a dog?"

I said, "This is for my special Purina Dog Chow diet. I just put some in my pocket and when I'm hungry I take some out and eat it. I was doing really great on the diet and lost tons of weight, that is, until I woke up one day in the hospital, with tons of tubes coming out of me."

"Oh!" the woman exclaimed, "Did the diet make you sick?"

"No," I replied, "I got hit by a car chasing a cat across a busy street..."
