(We have a display of TVs that are tuned into a news channel. The story on the television is about a drug smuggling tunnel underneath the ground that crossed the US & Mexico border. One of my coworkers, who just started working the previous week, is watching it, puzzled.)

Coworker: “I just don’t see what the big deal is about this.”

Me: “You mean besides the fact that they’re smuggling drugs illegally across the border between two countries?”

Coworker: “No, they’re not. It says it’s between Mexico and Texas!”

Me: “Yeah, it is. Mexico’s not part of the United States.”

Coworker: “What are you talking about? Mexico is totally a state!”

Me: “How many states do you think are in the USA?”

Coworker: “57!”
