A construction worker tells his doctor, “I’m constipated.”
The doctor examines him for a few minutes and says, “Lean over the table.”
After he does so, the doctor whacks him on his ass, with a baseball bat. A loud “CRACK!” is heard, and the doctor sends the man to the bathroom.
After coming out of the bathroom, the construction worker says, “I feel great! What should I do to prevent constipation in the future?”
The doctor says, “Stop wiping your butt with cement bags.”
