My husband had an ad on CL recently to pick up scrap. He got a phone call this week for some cars, aluminum, and copper. He called the guy back yesterday about it and it was someone playing a joke on someone else. He gave the poor guy that the joke was on the number of who called. Thankfully that guy was very nice and appoligized about it. If it was my husband that the joke was on he probably wouldn't have been so nice.
