Really Sick

There was this guy who was sick,so he went to the doctor.

The doc ran some tests and sent him home with some medicine.

The next day the doctor called and the wife answered.

"I'm going to need to run a few more tests", the doctor said.

"I'm going to need a semen, urine and a fecal sample".

After she hung up the husband asked, "What did the doctor say?"

"He needs a pair of your underwear".
