Face off ... Craig and Freddie
FREDDIE Fisher was put through his paces when he took on series one winner Craig Phillips in an assault course.
The beefy scouser re-entered the Big Brother house this afternoon as part of the show's 10th anniversary celebrations.
Past housemates will enter the house everyday and compete against current housemates in a series of challenges.
The current housemates must win seven of the nine activities to land a luxury food budget for next week.
"You and I have something in common," Craig said as he shook Freddie's hand, "we've both been nominated the most."
As Craig stood at the start line Freddie, 24, begged him to take it easy.
The 37-year-old replied: "I'll take my time as you need to eat."
Freddie seemed to come undone when he fell off the seesaw and had to repeat the apparatus.
But he managed to compete the course - although the winner is yet to be announced.
Dean O'Loughlin, from series two, will be taking on the second of today's three challenges - a sugar-stacking contest.
