A greek tragedy unfolds when an invisible man falls into a hole and learns how to turn other peoples lights off by remote. He sends Mr Blobby’s less evolved cousin to apologise but that’s not enough to stop a delegation of medical professionals from jumping in the hole and throwing musical instruments at him. No one helps him though, because the Brigadier’s brain has gone to the seaside and Jo is wandering in the desert having killed a muppet, wearing it like a second skin.

Happy Anniversary!
