Actually yes, an old girlfriend had this; her part time job was some kind of secretary thing where she used both a calculator and a phone and would mix the stuff up. Well, she just at one point ripped off the keys to the calculator, I'm talking like one of the old ones with the paper that comes out of it and ****, and rearranged them to be like a phone. The problem was, of course, they were still the same numbers. She asked me how to fix it and I told her I don't understand that kind of stuff, so she put em back. Should be simple on a computer though.
