As stated in the episode recap, there is a "Slip-n-Slide" type competition going on right now, with everybody navigating across "ice" to fill jugs with water (or some sort of liquid). Besides winning HOH, each person can instead go after either safety from being nominated/evicted this week or a cash prize of ten grand that was voted on by twitter followers.
The first victory came pretty quickly, as Britney decied to go after safety.
Shane is in the lead for HOH, and Boogie will probably get the cash.
Boogie won the cash.
Minutes after Ian said he peed his pants (but as joking), Shane won. How exciting.
