Tonight’s episode features the 4th eviction of the year. Jessie Godderz, the natural bodybuilder, and Memphis Garrett are both up for eviction. The events in the past week have split the votes. For the first time since Big Brother 1 America casts the deciding vote via Dan Gheesling, America’s Player, of who stays and who goes. We’ll see if Julie Chen plays that up on the live broadcast.

Tonight’s Head of Household competition will involve the Wake-Up Calls that fans have been sending into CBS.com. The houseguests were woken up last night every 10 to 15 minutes by messages from the outside world.
