The Kardashian sisters have been pretty outspoken about their disdain for sister Kourtney's baby daddy Scott Disick, but after they see what he did at his birthday party, it might be the final straw.
In a sneak peek obtained by RadarOnline.com from the hit show Keeping Up With the Kardashians, Kourtney and Scott are discussing a possible move to New York.

"Scott loves living in New York," Kourtney says to the camera. However, with her whole family in Los Angeles she is reluctant to move.
The parents of little Mason were celebrating dad Scott's birthday in New York when he gets up to blow out the candles on his cake.
"I know it's bad luck to say what you wish for," Scott says to the group of friends. "My wish is to get the hell away from her family in California and get to New York where my family is."
A shocked and angry looking Kourtney says "What a great wish."
