Carbon Tax or Carton Tax (TBAG)

I'm confused, recently I went to the grocery store to buy a package of chicken eggs. I use them to throw at highschool principals and build biodegradable automobiles. Anyway, when I bought these eggs, the clerk said, "that'll be $4.75."
I said to him, "that's expensive for eggs, especially when I told you I don't even want the yoke."
He then told me about a new carton tax: applicable to all cartons, including milk, egg, and cigarettes. I thought to myself, "what's next, an 'income' tax?" I was later told it already exists, and the reason I don't know about it is because I don't have an income, not a job. Instead, I trade advice about past events for money.
So I accepted the clerk's total, tossed him a bag of pennies and told him to "copper" feel.
