So many different phone scams now.
First off, the number comes up with the same numbers (almost) as mine. You answer, there's always a delay and then a robovoice about:
CRA
Warrant for my arrest.
Social Insurance number has been compromised
Usually what I do is accept the call, but half the time they hang up the moment they hear my voice.
If they do engage in conversation, I will ask them what they want. Then I will say "hang on a minute"
Then I will come back and say, "sorry I was busy fucking your wife just then, what do you want again"
Now they know you're not fucking their wife, but he heard it. And I may get really graphic and tell him that he's not satisfying his wife in bed and she loves big cock, etc etc.
And if he hangs on I tell him "you know your wife hates your mother don't you" (which is probably really the case) and it will torque him right up.
