Corey has never been a Big Brother player lauded for his smarts, but he hit a new low this week. After Nicole convinced Natalie to turn on Paul and Victor, Corey became so comfortable in the house he seemingly forgot there was still a competition going on. [...] that nonchalance has come back to bite him, with Corey now sitting on the block in major danger of eviction. When he revealed why he didn't bother studying for the Veto. How has he not realized what's happening yet? Big Brother airs Sundays and Wednesdays at 8/7c and Thursdays at 9/8c on CBS.
