Ward 40

 When in the hosp'tal '91,

 Major brain surgery,

 Small wards they had, same gender,

 Another five and me.

 Each morning, 'observation check's

 The nurse would, question, ask,

 "Mr. Ross, d'you know where you are?"

 It was a daily task 

 Ward 39, was where I lay,

 Across the corridor,

 In ward 40, were females, six,

 Each morning, would implore. 

 Whene'er, each morn, the question asked,

 A fun game, I would play,

 "I'm in ward 39, though I

 Want to be in 'forty'.

 Coming out of anesthesia 

 After my surgery,

 Th'observation question,asked,

 To check my memory.

"Mr. Ross, d'you know where you are?"

 My usual response given,

 "You're actually in th'recovery ward"

 My memory safe, was proven.
