6. Big Brother 2
The second season of Big Brother showed us exactly what to expect from the series as a whole. Shannon using Hardy’s toothbrush to scrub the toilet bowl and many other hijinks made for major water cooler moments. Of course, easy-on-the-eyes Dr. Will Kirby (above) was also a consistent draw, making it all the way to the end for the win.
