Where do they come up with this stuff?

Just a quick laugh.
My 2 year grandson is obviously learning the difference between boys and girls. The story goes, I was at his house playing with him and his little sister Mya (who is 3 months) my daughter and her husband were both there and we were all in the living room. Well except Mason, he was in his room playing. We were all just sitting around talking and playing with Mya and in runs Mason. He comes right up to me and says, "Ninnie, do you have a crotch or a ding ding?" My mouth agape a little I just look at my daughter, it seems she and her husband didn't hear Mason so Mason asks again, "ninnie do you have a crotch or a ding ding", with little hesitation he continues, "My daddy has a big ding ding." I am not sure what I did or what my son in law did at this point, but I can tell you it is hard to look at him now. Then quickly Mason says, "I have a ding ding, not a big one yet, Mommy has a crotch, Mya has a crotch. What do you have Ninnie, a ding ding or a crotch?" At that point I just said "crotch". He seemed happy with the answer and ran back into his room to play.
Anyone with children know you never know what will come out of their mouths at any given time.
