My puppy always starts to growl as soon as he's asleep:
"I've caught a hundred waterfowl and killed a thousand sheep;
I felled and ate a buffalo, then swam across the sea,
And when I found where squirrels go, I chased them up the tree!"
And though his dreams are not the truth, who'll wake him up? Not I!
I've firmly held it since my youth that sleeping dogs should lie.
