A teacher misunderstands the job, an actor searches for the perfect last words, and the late, great E M Forster pops up in the wrong century. Plus: an ambiguous fire drill. And who's the daddy?

The disturbing side of communal living, and a surprising way to assess new teachers. Parents deal with an unusual announcement about their daughter's sexuality. And some aliens pitch a new sitcom.

The real cause of climate change? It's good news and bad news. Plus: TV's most wholesome heirloom repair show. A death in the Sweary Aussie family. And the lawyers intervene in the writers' room.
