what our vanity license plate really means

We went to visit our son in college yesterday, a short and pleasant drive, usually...  The boys were fighting in the car before we even left the driveway. My husband tried all the usual forms of entertainment and nothing was working. They were still  arguing ..and about important things in life too, like how his leg keeps touching mine kind of stuff. All those travel happily with your kids in the car games were just not cutting it..way too old for alphabet games... My desperate husband  resorted to making vanity license plates from every license plate we saw...this was  maybe more competitive and so lasted at least 5 minutes...one of the boys said, "Dad, if you had a vanity licence plate, what would it say?"  And without missing  a beat, he replied, "HELP"
