Expat - Loved your story. I had a similar experience as a kid.
Our phone number was almost like Wesern Auto. We frequently got calls. Dad would tell them they got the wrong number, give them the right one and hang up. I guess he was tired one night. We got a call and the other party asked if we still had the medicine cabinet on sale, if so, they would be right over. Dad asked if they wanted him to take the medicine out of it first.
Chico & sichuan - Maybe you guys need to "get a room". :) :) :)
