It appears that we have another musician in the family.
Although not a very good one.
Seven was just "rapping" the following song:
Yo, yo, yo
My name is Joe
I broke my toe on a Cheerio.
How does one break one's toe on a Cheerio? I have no idea, but this little rap has become Seven's new favorite song. He says he learned it from his good buddy, J.C. so I know why he was singing it.
Because J.C. is just that cool.
