Its funny my phone has caller ID so I know when I get an "Overseas" phone call and ever since I started answering the phone thusly:
me: Hello
them: Hello am I speaking to mr or mrs xyz
me: (putting on a posh british butler type voice) I am sorry the master and mistress are currently in the dungeon preparing the goat to be sacrificed to bealzebub....if you would like to have your name added to the list of supplicants I am sure they would be willing to do so...............
Curiously they hang up and never ring back. I wonder why?
