"How Santa REALLY knows.." joke

You'd better watch out,
You'd better not cry,
You'd better not pout;
I'm telling you why.
Santa Claus is tapping
Your phone. He's bugging your room,
He's reading your mail,
He's keeping a file
And running a tail.
Santa Claus is tapping
Your phone.He hears you in the bedroom,
Surveills you out of doors,
And if that doesn't get the goods,
Then he'll use provocateurs.So-you mustn't assume
That you are secure.
On Christmas Eve
He'll kick in your door.
Santa Claus is tapping
Your phone.
