Personally, I am constantly seeing some sign on a road where, in passing, my eye-brain combination not only mixes things up. but occasionally inserts words (often with a spicy, dirty, or irreverent bent) into my instant interpretation, which makes me burst out laughing.
When asked, I explain it to my wife, who then rolls her eyes in a good-natured exasperation...:)
Creativity is good. Chicks don’t get guy funny often.
