Daddy, What's a Joint?

The other night at dinner Michael had to finish his Explode the Code, which is a workbook that combines spelling, grammar and all that English jazz. He asked Aron what a joint is.

Aron told him it's like a bend in something, like where your elbow is or your knee or your hip.

Then he said, "and" ...

And I thought he was going to say something else, so I said, "Michael, let me tell you about my childhood and the definition of joint."

But no, Aron told him it's like a joint checking account.

I could not resist and had to give him the THIRD definition of a joint so he is not that socially awkward homeschooler we all hear about. I told him it's a marijuana cigarette. They vaguely know what that is, only because every now and then when we are out they hear me exclaim,

"I smell pot! I'd know pot anwhere! I've never been high. I wish I could get high because I would be less high-strung, but it's illegal and I am too attached to you guys, so I'm not getting high. Anyway. How 'bout those Chiefs?"
