29. The return of the Mac!
The rock-star dentist had been on Austin's radar for quite some time, but was continuously able to save himself from eviction.
Unfortunately, Johnny Mac's time in the BB house was up when Austin became HoH for the second time and opted to extract the dentist from the competition—or so he thought. After leaving the house, Johnny was able to re-enter the game when he beat out the rest of the jurors during the "Dizzy Land" HoH competition.
