I like number plates that are funny. I saw one that said my dog is cuter than yours, and I saw another one that state I am cute you are ugly.  I thought those were so funny.  I don’t think I would purchase any of those types. I think I would be subjected to stare, and probably obscene gesture. I would not want a driver to be so caught up observing my vehicle that they rear end my car. I think having funny sayings are hilarious, and they make a statement that the driver is a fun individual.  He or she is probably adventurous.
