Gooda Haver

We went out to lunch with Mike yesterday. After lunch, we were getting in the car and Mike told the kids to be good and have good behavior.
A few moments later, James asked, "Where are we going?"
Me: "Uh, home."
James: "Where we going a gooda haver?"
Me: "What?"
James: "Where we going a gooda haver?"
Mike: "What?"
Me: "Gooda haver?"
Mike: "He thinks you're going somewhere because I told him to have good behavior."
Yep. Gooda haver. So glad James understands what we're talking about. Ha.

p.s. Here's Nate's email reply:
That's probably about how I will be with my English when I get back.... I'll have to learn some things over again.
