Licence Plates and Diapers?

On my way home from work today, I saw a vehicle with this licence plate: 2WDS4U.
I thought it was quite clever.

I have decided I like the smell of disposable diapers. They smell, obviously, like baby or I guess baby smells like them. When we were waiting for our little guy to make his appearance, I had the top drawer of his change table filled with everything I might need - lotion, shampoo, body wash, a package of newborn disposable diapers and wipes. I loved opening that drawer and letting that smell waft through the room. Baby. It can only be described as baby.
