An Unexpected Wind

You see it happened as an accident
I really didn’t mean for it to occur
But last night I ate so much pork
That it all became a blur
I was just waking up
And stretching out from the cave
I heard a sound from behind
And the knight was no longer brave
It’s a little late now
And the point is probably mute
But when I stretched this morning
Out came the loudest toot!
