Alpaca Wacker

Mrs Brown has a problem with alpacas;
She's an alpaca wacker.

PC Smith likes alpacas and won't tolerate that sort of behaviour;
He's an alpaca wacker smacker.

Barbara loves alpacas and supports PC Smith in everything he does;
She's an alpaca wacker smacker backer.

Barbara's pet duck, Donald, likes to quack at her;
He's an alpaca wacker smacker backer quacker.

Little Johnny is a keen duck spotter;
He's an alpaca wacker smacker backer quacker tracker.

Sergei wants to hack into Little Johnny's duck database,
To covertly monitor local duck populations;
He's an alpaca wacker smacker backer quacker tracker hacker.

Sergei's in a human pyramid display team, directed by Sandra;
She's an alpaca wacker smacker backer quacker tracker hacker stacker.

Sandra's so small that Stefan put her in his suitcase in a moment of confusion;
He's an alpaca wacker smacker backer quacker tracker hacker stacker packer.

Stefan the alpaca wacker smacker backer quacker tracker hacker stacker packer
Packed away Sandra the alpaca wacker smacker backer quacker tracker hacker stacker,
So Sergei the alpaca wacker smacker backer quacker tracker hacker was stacked unsafely and fell.
Little Johnny the alpaca wacker smacker backer quacker tracker's computer finally worked,
So he found Donald the alpaca wacker smacker backer quacker and took him home with him.
So nobody quacked at Barbara the alpaca wacker smacker backer, who felt sad about this,
And couldn't attend the alpaca rallies to back PC Smith the alpaca wacker smacker.
So he lost confidence to smack Mrs Brown, the alpaca wacker.
So, the alpaca wacker wacked an alpaca, who attacked the alpaca wacker.

Or did it?
