After Khlo and Scott get tired of hearing about Kourtney's expert sailing skills, they finally decide to call her bluff...and why not? They're spending the summer in the Hamptons and just so happen to be living on the water.
"Today is the day I'm calling Kourtney out," Scott explains, in this sneak peek from Kourtney and Khloe Take the Hamptons. "She's not a sailor, I know she's not a sailor...I got a sailboat, it's at our dock, I need to see if she can sail."
You can probably pretty much guess how it all went down, which makes it even more fun to watch because, let's be honest, if she hopped in there and totally owned it, it wouldn't have been as interesting.
