Oh, that's hilarious.
I'm having a flashback ... some years ago when I first moved out here (some 900 miles from my parents), my younger brother (7 years younger) was still living at home. Brother had a girlfriend who would provide 'wake up calls' ...
Well, one afternoon, I wanted to call my parents to convey some information to them (I forget what ... this is almost 20 years ago, but it was important at the time), and they weren't home ... but brother was (and sleeping). So he answered the phone, and I'm getting these half-coherent responses and I'm paying long-distance prices ... I tell him not to answer again so the machine can get it, hang up, try again ... and he answered the darn phone *again*. I was finally able to get through around 9pm and reach my parents ...
All of which made me conclude that no one who lives in a house w/ other people should be getting 'wake up calls'.
But my mind is still boggled by the request in the OP.
