back in the old days my wife would never look up a phone number in our address book. Instead, she would just ask me the number since i was good at remenbering phone numbers. I warned her about asking me for phone numbers all the time so, one day she asked for my sisters phone number and I purposely changed the last diget of the phone number. So... She calls the number and then speaks to the person, Not my sister for over ten minutes. i am sitting right there watching and listening to the conversation. Awe struck because i know i gave her the wrond number. Until, finally she reaziles that the person she is talking to is not my sister. WTF................. and very funny.
