When I was a kid, I would read product labels. I noticed that a lot of the glass bottles had "ME 5c Deposit" written on them.
I was a really screwed up kid. I knew what bad grammar was *before* I learned that states had abbreviations.
So, I would wonder why they didn't write "I am a 5c deposit," instead of talking like a caveman.
