A man came home from work, his wife said, "you look bad". He said "I feel good".

Later that night he went bowling.

His friends said "You look bad".

He said, "I feel good". Puzzled, he decided to see a doctor.

When he arrived at the doctor's office, the doctor said "You look bad". The man said, "That is what everyone keeps telling me, but I feel good". The doctor began to consult a medical text, all the while mumbling to himself "Looks bad but feels good". At last the doctor exclaimed "I have it, you are a v****a!".
