I don't know the episode, but the tickle contest maybe takes place when both teams are placed in one house. According to Wiki, Britt isn't in the house until episode 3 (day 16). So the tickle contest after episode 3.
Then the opposing team (Norway) got tickled?
Been looking for this for a while, one of my favourite mainstream scenes. Pity they don't do stuff like this more often.
Good clip! Didn't know they did this on ordinary TV back in my old native Sweden.
I really like the reaction from the girl on the left watching at 00:24.
She did well holding out that long, no wonder she was worn out at the end of the clip. Didn't think a mainstream scene would go nearly that long. Now if only there was a full recording...
