Swim with Dolphins (S02E03)

Ricky Gervais and Stephen Merchant send Karl to Australia to swim with Dolphins. Along the way, Karl has an extended stop in Thailand where he gets a makeover by the local lady boys, takes part in a special Thai boxing match, spends time in a village inhabited by 100's of poisonous snakes and gets robbed by monkeys. Once in Oz, Karl discovers that, although he is diving with something, there's not a dolphin in site. (Prime Video)
