Joke

I had ordered vanity plates to go with my very first car and proudly did the installation myself. When I finished, my father came outside and asked, "Why did you put on only one?"
"That's all the state sent me," I replied.
"Is that right?" Dad said with a grin. Kneeling down, he quickly undid the screws and slid a fingernail along the edge of the plate, separating it from the one underneath.
The name on my personal plate? DITZ E 2
