Note to self: don't fall asleep around Ruby and Kimberly Stewart!
In a preview clip from this Sunday's episode of Stewarts & Hamiltons, Sean Stewart falls asleep in the car with his two sisters during their trip in Haiti.
"Should we draw wieners on his face?" Kimberly smiles. "Yeah!" Ruby responds as Sean lies sounds asleep.
"Do you have a pen?" Kim asks as Ruby takes out a marker. "Right on the cheek!"
"Sean falls asleep everywhere so it's just like you have to draw on his face," Kim explains. "Like don't fall asleep with your two sisters in the car. Obviously that s--t is going to happen." Obviously!
The trio then goes on an emotional tour of a damaged golf course, all while Sean still has penises on his forehead and cheek. It isn't until the end of the tour that the group lets Sean in on the hilarious prank.
"Thank you so much for having us, both times," Kim says to their guide before cracking up at Sean.
"What are you laughing at?" Sean asks. "Look in the camera!" Kim cries.
