Stewart Henderson presents another sparkling series of Questions Questions - the programme which offers answers to those intriguing questions of everyday life, inspired by current events and popular culture.
Each programme is compiled directly from the well-informed and inquisitive Radio 4 audience, who bring their unrivalled collective brain to bear on these puzzlers every week.
In this week's programme Stewart helps a listener who has long been mystified as to why bacon comes in rashers but everything else in slices. He finds out why so many Greek theatres were built close to the coast and about a strange seaside phenomenon, the mechanical elephant. And, with Buster Keaton in mind, he discovers how fast a car would need to go to lift you off your feet and fly you horizontally behind it!
