Is it better to drink from a mug than a glass? Should couples have separate beds? Does the Happy Birthday song need to be changed?

These are the existential questions that Austin Butler and Zoë Kravitz have to ponder during a game of "Unpopular Opinion" on BBC Radio One, which sees members of the public calling in to give their most controversial opinions on a variety of topics.

The clip above is less combative than some we've seen in the past, with Kravitz and Butler largely taking the side of the callers before everything goes off on an unpredictable (but excitable) tangent about Pitbull concerts.
