HEY YOU, JOIN THE NAVY!

When I was a kid, we would sometimes have dinner conversations backwards. We wouldn't try to pronounce them backwards like this reference - we would just spell our sentences backwards (including punctuation for clarity). One time a cousin came to have dinner with us. We persisted with the tradition and the cousin was thoroughly confused by it.

I haven't thought about that for years. I enjoyed it a lot and I think my siblings did as well. I don't remember how it started, but I wonder whether my parents started it to help us kids learn spelling and grammar.

"you" is wrong, it says yuo.
