We sang it this way —
Leprosy, Oh my Gosh I’ve got Leprosy
My eyeball, fell into my Highball
Leprosy, Oh my Gosh I’ve got Leprosy
My ear, fell into my beer
Leprosy, Oh my Gosh I’ve got Leprosy
My nose, fell into the hose
Leprosy, Oh my gosh I’ve got Leprosy
My spine, fell into my wine
... make up whatever rhymes, usually some sort of drink
Cackle cackle...
