I have a rather immature sense of humor, so I laugh at things like license plates that say something inappropriate or possibly offensive. Others don't, so the state actually has employees that rule whether or not every single personalized license plate request in our state is OK or not.
Surprisingly, only 84 requests in the whole state didn't make the cut in 2017.
Our friends at the Denver Post have a list of all the ones that were rejected. Be careful as some may be offensive to some folks. See the list here.
