Great Dog Convention . . . there's an explanation for everything

Great poetry . . . from the early 1900's

The Dog Convention
There was a Great Dog Convention.
They come from near and far.
Some came on bicycles,
and some they came in cars.
Y'know, before they could enter,
or even take a look,
they had to take their asshole off,
and hang it on a hook.
But before they even got seated,
(every mother, pup, and sire),
An old dog hollered from the back,
Run for your life. It's a FIRE!
The crowd of dogs began to panic,
and nobody stopped to look.
They grabbed the very nearest asshole,
off the very nearest hook.
And this is why, even today,
a dog will drop a bone,
to sniff another doggie's butt,
to see if it's his own.
