Completely seriously; while I’m sure essentially no one actually does, the IRS is not going to like network with the FBI or your local police department if you, for some reason, decide to pay taxes on your weed sale profits. Unless you report that you’re selling sex slaves they seriously could not care less.
I know it’s just a joke image but I do love the idea of someone who makes much of their money illegally but also has this very honorable commitment to paying their fair share in taxes.
