The HouseGuest who I consider to be the most entertaining is the person who will forever be a staple to the season in my mind. This person completed the storyline of this season, and it wouldn't have been the same if they were not here.
The Underdog Award goes to the HouseGuest this season who I personally think had a difficult road to run over their time in the house. This HouseGuest was also entertaining, and let me know JUST how hard of a time they had.
