This week on Yes or BS, we’re covering everything from Star Trek to nuclear warfare. Never let it be said we’re not eclectic. Among the facts you’ll have to decipher this week is a tale about a group of Spanish guerrillas, who may or may not have been terrorized by unseen demonic forces during the Napoleonic War. Was a nuclear explosion narrowly averted by a North Carolina plane crash? Was there a 1920s craze for oxygen-depriving ‘isolation helmets’? And did a 19th century anatomist publish an account of a local murder case in a book bound with the murderer’s skin? Think that all sounds a bit too macabre? You can blame Anthony. But don’t worry – there’s also a fact here about domestic cats, the naming conventions of astronomical objects, and, er... Mr Spock.
