Walking through a rough part of the city one night, two social workers heard moans and groans and muted cries for help coming from an alley. Walking toward the sound, they found a semi-conscious man.

"Help me!" he said weakly. "I've been mugged and viciously beaten!"

The two social workers stared at him for a moment then walked back out of the alley.

One turned to the other and said, "You know, the person who did that really could use some help!"
