The Corked-up dog

There was a dog who had to fart
And then he met a boy named bart
Who told that very crazy mutt
"You have a cork stuck in your butt!"

They pulled and pulled to no avail
Until they felt that they must bail
For that cork was in oh so deep
And then the dog let out a peep

A peep of hope, a peep of grace
And then the dog scrunched up its face
And let out a so strong a fart
It sent the cork come tumbling out.
