A man went to the doctor and complained that he had the most terrible constipation.

The doctor examined him and then gave him a prescription for some tablets to be taken last thing at night.

2 weeks later the patient returned for a check-up and the doctor asked him how his constipation was.

The doctor was rather surprised when the man gloomily answered that the pills worked fine and that he went every morning at 7.30.

"So why the long face?" asked the doctor.

"Because I don't get up until 8 o'clock ! ! !" replied the patient.
