A verse I remember (although it has a different rhythm):

We let you use our new cow milker
You didn't know the hose from the spout
You left it on our old cow Bessie
By the time we got back she was turned inside out

My wife contributes this one:

Remember when you went out huntin' for 'possum
you said you'd get one and wouldn't be long
That's ten years ago, an' I'm sittin' here waitin'
Beginning to wonder if something went wrong
