Jay Leno Asks Kourtney Kardashian: Which Kardashian Sister Is The Smartest Of Them All?

By Nuzhat Naoreen

Now we've always known that the Kardashian girls were some of the savviest business women out there, but have you ever wondered which of the sisters is the most intelligent?

Last night, during an appearance on the "The Jay Leno Show" (maybe you've seen it in the headlines lately?), Jay asked new mom Kourtney Kardashian which of her sisters is the most book smart. Kourtney, who was in the hotseat for Jay's Ten@Ten segment, during which a celeb has to answer 10 random questions, barely hesitated before answering.

So, who'd she say was the smartest? Well, umm, herself. OK, so maybe the girl's just a little bias. After herself, Kourt (who, by the way, looked great in a black and brown printed top paired with long necklaces), said Kim was the smartest of the girls, followed by Khloe and then her two youngest sisters Kendall and Kylie.

Hmm, we wonder how her sisters are going to feel about the ranking.

Of course, that wasn't the end of it, Kourt also had to answer nine other random questions, including what her superstitions are (she makes four wishes at 11:11) and what her worst job was (production assistant for a film).

One of our favorite stories of the night came about when Jay asked Kourt about her best breakup. Turns out Kourt had Kim breakup with a boy on her behalf via answering machine when she was in 9th grade (somehow we can totally envision that as a future episode of "Keeping Up With the Kardashians", except maybe with Kendall and Kylie!).

We also got a kick out of the fact that Kourt was shocked to find out her bro-in-law Lamar Odom actually played on the court when she went to watch one of his games. Apparently, she figured he sat in the sidelines the whole time.

The smartest sister of them all? Yeah, about that...

Do you agree that Kourtney is the smartest of the Kardashian girls?
