'Big Brother': Ian's Bizarre Antics Upstage First Nominations And The Coach's Challenge (VIDEO)

Ian is a self-professed "super-fan" of "Big Brother" (Sun., 8 p.m. ET on CBS), so shouldn't he know about the live feed into the HOH Room? Apparently, he forgot about this little detail, as he was up and cavorting around the house doing some very strange things in the middle of the night.

He thought no one could see him, but coaches Britney and Janelle were up in the HOH Room with current HOH Willie, and the three of them were mesmerized by Ian's bizarre behavior. Throughout the episode, though, Ian's behavior became more and more creepy and off-putting to several of his fellow contestants.

Luckily, his coach won the new Coach's Challenge, and wisely gave Ian immunity for the week. That left Willie scrambling to figure out who to nominate. As Britney and Janelle have their teams working together, Willie targeted what he saw as the strongest players on the other two coach's teams: Kara and Frank.

"Big Brother" continues with the Power of Veto competition on Wednesday at 8 p.m. ET with the first live eviction the following night at 9 p.m. ET, and then back again on Sunday at 8 p.m. to round out its thrice-weekly schedule.
