I remember a Texas plate HMFIC2. Most Army veterans will quickly translate this (could have a racial slant) but why Number 2?
Second car
I think it means he is #2, probably after his wife.
Long ago, at a job in high school, we were laughing about someone being HMFIC, and a black guy chimed in and said that the HMFIC's boss was the HNCIC.
CIC was "Completely In Charge". I'll let you fill in the rest.
