I have a somewhat-common first name and a very common last name.
Many collection agencies seem unable to grasp the idea that more than one person can have the same first and last names, even though we have different DOBs and SSNs.
Also, I once got an anonymous voicemail that said I should get tested for STDs if I was the [firstname lastname] who hooked up with Wayne in the parking lot of a Flying J truck stop. (Nope, not me.)
