cranker and canker

cranker had a canker sore
he kept it in a jar
he took it everywhere he went
he took it near and far

he'd take it out to do some tricks
like a performing flea
the audience would gather round
his looking glass to see

he'd never put it in his mouth
for that would cause him pain
plus all those shows the canker gave
meant some financial gain

the intrepid sore just wanted back
inside the mouth of cranker
and on a flying loop-de-loop
lit on his tongue, that canker

now the sore just causes pain
and doesn't do its show
and cranker applies anbesol
and hopes the sore will go
