Faults in Training

I taught my dog to retrieve the paper,
But when he brings it it's torn and tethered,
with a little bit of drool
but he brought it ain't that cool?

I had my parrot learn new words,
"Say, Polly wants a cracker," I said and rehearsed
He squawked and pruned his long feathers,
then said, "Crack Heads wear black leather."

I wanted my fish to come to the top of the tank,
whenever I fed it but it always turned and sank.
I went to fetch it out one day,
and out come a fishy baby.

Now my cat was smart so I got it to say,
"Meow meow," when it would play.
The bad thing is it won't stop
Now it "Meows," a whole lot.

I wanted my horse to learn to bow,
I knew I could teach it somehow,
When he finally kneeled by the cart,
he let out a great big fart.

Now my animals all do tricks,
but I have a few things to fix
I don't blame them it's not a brain thing,
its just some faults in they're training.
