This is generic but it reminds me of a joke. This guy was standing in line at the grocery store and the gal ahead of him was buying Purina Dog Chow. Sez the guy, "I once went on a diet eating nothing but Purina Dog Chow."
"How did it work?" inquired the lady.
"It worked well, but I had to quit when I landed in the hospital," he said.
"That's terrible," she exclaimed. "What happened?"
"I was lying in the street, licking my balls, and I got hit by a truck."
