At lunchtime, a man who worked in an office felt really lousy and decided to excuse himself and go see the doctor.
On entering the surgery, the man cried:"Doctor, Doctor! You've gotta help me! I feel flushed, I have a fever, headache, muscle aches, chills, I'm tired all the time and I have a dry cough."
"You must have flu." the doctor said
"No, I walked." our patient replied.
