Knock-knock whose there?
It's your liver
Liver who?
Liver who about to leave you soon
On a ladder to heaven
Bladder alongside,you won't make 27
Snouts-snouts,you getting high,fogging
Snorts-snorts,for air you gasping
Cough-cough,but you still gassing
Puff-puff,your lungs caving in,death calling
Cancer creeping in,life seeping out
Drop-drop,dead in your coffin
