This could be an argument for never being nice to anyone on the phone again...

There's a new phone scam going on where the first thing the person asks is,

Can you hear me?

Your instinct will be to say, "Yes" . . . and if you do, you're SCREWED.

Because they're recording you saying 'Yes' . . . so they can play that back when they use your stolen credit card number to buy something and the credit card company calls to confirm the purchase.

So if you get a call that starts off with 'Can you hear me?' just hang up.  Or if you think it MIGHT be a legitimate call, don't say 'Yes' . . . say something like, 'I can hear you.'
