I found Burt whacking his PP incredibly funny, but it it's just a few short minutes out of a 24 hour cycle.
I think that Management is trying to slow their roll and not have a ton of people drop out in the first week. These aren't ordinary Fish; they're silly, spoiled wannabe "influencers" who can't and won't take a beating like the fish from the last two seasons. Can you imagine them boxing each other because Sam told them to?
These Fish think it's all about duplicity and alliances, they're not expecting it to be a physically grueling challenge like the earlier seasons were (especially Season 2).
