I NEVER EVER answer my phone to an unrecognized number, especially when it comes in at 0432 hours in the morning.  Some telemarketing scum must have really f***ed up their robo calling hours for that to happen.  A quick call back to the number (just in case it was an emergency and they happened to dial a wrong number) confirms it's a scam.  "The number you dialed is no longer in service".  Sometimes I really wish that some jihadist would go into a telemarketing building and scream, Allahu Akbar, boom.  Somehow I don't think anyone would give a rats a**.
