Conversations in the car

Here is what I overheard on the way home from the lake on Sunday:

Brian: Who can tell me one organ of the body?
Liam: HEART!!!
Brian: Yes, good job. What does the heart do?
Connor: Pumps your blood.
Brian: Yes, who can tell me another organ.
Silence
Brian: Can you remember another organ?
Liam: Balls!
Snickers from me and Brian in the front.
Brian: Well, that's not exactly an organ, but what do the balls do?
(Okay, I might have used this opportunity to correct the terminology, but whatever.)
Liam: They hold your babies.
Brian: That's right, Liam, when you get older, that's what helps you make babies.
Connor: Does mom have balls? (Again, I'll resist the urge to point out how big my "balls" must be to take on four kids, but whatever.)
Brian: No, mom has a uterus.
Connor: Hey, no fair, I want a uterus!
More laughter from the front.... more laughter. And now we are dissolved into tears and trying to recover because Connor sees he's gotten a laugh and is saying over and over again, "I want a uterus."

There's just nothing in the world like hearing your four year old son say the word, "uterus". Now, I wonder what this is going to do to their concept of gender as they grow? :) I promptly ordered them a book called, "My Amazing Body" that has all sorts of information on the "organs" of the human body! :)
