that makes your granddaughter very very happy, as that is one of her top 5 favorite songs. LOL Not your usual 8 yr old...
your grandson seems to like the song too. He does the baby happy butt thing with the squating action, followed by mass excitement when his sissy laughs at his dance moves...which inspires him to try to clean my desk with flying arms. Luckily the water was in a plastic cup and missed my computer. My lap, not so lucky.
