I once had a license plate that read 123-PMS.
(I don't actually recall the numbers.)
Anyway. I noticed it as the guy from the dealership was affixing it for me. Like it was not bad enough I drove a mini-van. I had to get that license plate.
From time to time people would be driving beside me smiling and looking at me. I would forget about the humiliating plates and think, "Oh yeah. I have got it going on today. Other drivers think I am hot."
Then I would remember they were just laughing at my plates. Just thinking about PMS made me have PMS. Then I wanted to run them over for their heckling. And also because of their oh so normal license plates.
