I don't know what it is with the people I work with, but it seems like there are endless possibilities for funny things to happen regarding names.  For example: 

1. A few years ago I mentioned that my co-worker called another co-worker on the phone and said, "Hey Curt, it's Ernie."  To take it one step further, that same Ernie later worked on a project with a guy named Bert.
2. Two Asian guys in my group both have the last name Wong.  One of my co-workers said something about inviting them to a meeting, at which point another co-worker said, "Two Wongs don't make a White."
3. Just recently I overheard someone making a phone call who said, "Hey Ben, is Jerry there?"
