We got one the other morning. The caller was from India, clearly. Once I got him to understand that a, we were not buying anything and b, we would not give him access to any of our computers, he hung up.

The best I had recently was the package confiscated at customs from a diplomatic package but he made the mistake of giving a legit local phone number. After I called him and left a message he actually called me back to try to persuade he was legit. Guess who got reported to custom and the post office.
