So Kevin Jonas had his first kid at 26. If his kid has her first kid by 26 and her kid has their first kid by 26 and so on, then by the year 3000 Kevin Jonas’ great-great-great-grand daughter will be like 856 years old.
But, according to the song, she’ll be doing fine.
Good for her.
It’s even more far fetched when you realize the song was written by a British band before the Jonas Brothers ever releases a single song, and was release in 2003
