A man and his wife went to the doctor’s office and the doctor asked the man for a blood, urine, and feces sample.
The man was slightly deaf and said, ‘’What?’’
Again, the doctor said, ’’I need a blood, urine and feces sample.
The man still looked puzzled, so his wife leaned over and yelled into his ear:
‘’Sheldon, the doctor needs a pair of your underwear!’’
