First untruth?

Isaac knows he is only allowed to throw two things: balls of any sort, and the dog toy known as the moo-hah-hah. That doesn't mean he never throws anything else, though. I like to correct misbehavior by reminding him of what he is allowed to do, so when this happens I say something like, "No, we don't throw spoons. You can throw a ball, or you can throw the moo-hah-hah, but you can't throw a spoon."

Lately, though, all I have to do is say, "No. We don't throw spoons. What do we throw?" and he immediately answers, "Ball." Then, after a moment, "Moo-hah-hah." Sometimes I don't even have to ask -- right after I say "No," he'll say "Ball."

Last night, though, after Isaac had thrown his plastic shape-sorting toy, Craig tried phrasing his corrective questions a little differently:

Dad: No, we don't throw that toy. Is that the ball?

Isaac: No.

Dad: Is that the moo-hah-hah?

Isaac: [mischeviously] Yep.

Dad, Isaac, and Mama: [laughter]

Dad: No, it isn't the moo-hah-hah -- it's your toy. Now, do we throw it?

Isaac: Yeah!

Dad, Isaac, and Mama: [laughter]

Dad: Okay, yes, you did throw it ... but should you throw it?

Isaac: No.

Could calling his shape-sorting toy the moo-hah-hah have been Isaac's first intentional untruth? (I wouldn't call it a lie, exactly.) Was it at least an intentional joke? Or was most of this humorous (well, to us, anyway) exchange just a misunderstanding on Isaac's part? The difference between "Do we throw" and "Did you throw" is pretty fine, especially to someone who sometimes gets his elbow and his neck mixed up.
