WHEN HOBBIES GET STRANGE AND SERIOUS

PODCAST OF THE WEEK

- With KAY HARRISON

It's good to have a hobby, but these things can escalate, as American journalist David is discovering in his new show, speaking to guests about their niche interests, bizarre collections and all-consuming passions that have probably caused many a slammed door and ultimatum over the years.

Like actor David Arquette's obsession with Bozo the Clown, which led to him buying the global rights to the children's TV character. And 46-year-old reluctant influencer Jian Yang, who shares his home in Singapore with 13,000 Barbie dolls - the second biggest collection in the world, closing in on her Nol fan in Germany. Only 5000 more to go, Jian. Must try harder.

A new episode hears from author and librarian Rosie Grant, who's a proud "taphophile" (me neither, it's someone with a fascination with gravestones - a sort of tombstone tourist).
