Last year, 3 of us in the office were in on it and got the others. We changed my ringtone to a quacking duck then hid my phone up on the shelf. We took turns calling it and just letting it quack once or twice. Then when they would say did you hear that? We'd do different things. Like sometimes I would actually be calling it so they thought I was on the phone. Or we'd go to the ladies room and call and we wouldn't even be in the room. Then another time we'd say, hear what? Then we'd say it sounds like a duck or something. The trick was having it hidden not to close to their desks so with one or two quacks, they could never zero in on it. We finally had to tell cause on of the girls was getting up on the file cabinets and starting to take the ceiling tiles down!
