All The Best First-Time Moments Throughout Big Brother History

7/17

The first season of Big Brother All Stars

What happens when you take 14 former Houseguests, put them under the same roof, and have them compete for $500k? Three months of fun, strategizing, and a whole lotta drama!

Season 7 of Big Brother, commonly referred to as the All-Stars season, marked the first time the show's cast consisted entirely of BB vets. By taking the returning HGs prior knowledge of the game and combining it with their hunger for redemption—or, in Dr. Will's case, a chance to win again—made for a hugely memorable summer.

To see these pros duke it out, watch Big Brother Season 7 on CBS All Access.
