Scott Weintraub was a houseguest in Big Brother 4. He was expelled from the house on day 8 after going on a tirade following his ex-girlfriend Amanda Craig's entry into the house as part of the X-Factor twist, making him the second houseguest in history to be expelled, after Justin Sebik.
Note:1 Scott volunteered to sit out of the first HOH competition as the competition had to be played in pairs and their was an odd number of houseguests. Because of this, he was granted the power to choose the Head of Household: he chose Nathan Marlow.
However, unlike Scott, Brian and Kat were eligible to win Head of Household while Risha and her fellow houseguests were all made HOH for the week, whereas Scott had sat out of the competition and thus was not eligible to become HOH.
Scott is currently the only expelled houseguest to be expelled in less then 10 days.
