Three prisoners were trying hard to prove that they were imprisoned for a long time. 

A prisoner said ” I have been here even before the train was invented?

 ” No kidding! ” said the second one.” Well I came here when people use to travel on horses. “

The third prisoner said innocently ” What are horses? 

   A patient came to a doctor.  ” Doctor doctor do you recognize me “

Doctor. ” No ! who are you? “

Patient. ” I am the same person, who had pneumonia two years ago and you told me not to take bath.

I just wanted to know, Can I take bath now?
