next time you get a robocall....answer and say "FBI, how may I direct your call".I'm feeling pretty good now. Was in the middle of working on a project and got TWO spam phone calls. The first was a robot, so I hung up. The second was a lady trying to sell time share crap. She asked how I was doing, and I said "I'm F****g pissed off, because I'm trying to work here and you're interrupting me by calling!" and slammed down the phone.
Ah... stress relief is a good thing.
