Have you seen this video?
My daughter and nephew were playing it a few weeks ago. I have to admit, I laughed quite a bit.
Well, it seems this video has become inspirational. As we spent some time driving last week, the two of them started up with singing in a similar fashion with the things they could see around them, and then my son got in on it. I was cracking up! Anything they saw or commented on could be a part of it and it has become a regular activity since. Yesterday, we were stopped next to a vehicle and my son sang that the lady is driving a nice car. My nephew sang back, "No, she isn't." (LOL. Oh, man, the times you wish you had a voice recorder constantly on...)
