I have a son named David who worked on a surveying crew one summer with two other Davids. They were David, Dave and Davey.

One hot summer day they were on the front porch of a friend's house and rang the bell for a glass of water. The 10-year-old who answered the bell didn't realize that the intercom could be heard outside and called to her mother, "Mom, David ___ is on the front porch with two other strange looking guys!"
