On Wednesday night’s episode of the MTV reality challenge show "Battle Of The Exes" the last black contestant almost went home not because he lost a challenge but because his own teammate/ex-girlfriend mocked him with "one of the most offensive pranks" in MTV Challenge history. "The Challenge: Battle of the Exes," an offshoot from the reality series "The Real World" that puts former MTV reality TV show participants up against each other in grueling physical challenges. In last night’s episode a Southern "sheltered" white contestant named Emily decided to mock her African American ex-boyfriend Ty by dressing up in his clothes and covering her face in Nutella… aka blackface.
