Cough, sir?

I have a little cough, sir

In my little chest, sir

Whenever I cough, sir

I feel a little pain in my chest, sir

Cough, cough, cough, cough

There it goes again, sir

I have to thank my Primary 2 english teacher, Mrs Chong (coincidentally, she used to be my sissy's form teacher!) for drilling this cute little poem into my then cute little 8-year old head. Guess what made me think of this poem right now?
