Air Tennis?

At Taj Connemara, a 5-star hotel in Chennai, I saw this guy with a flourescent green racquet that looked like the cheap bats for kids available in Pondy Bazaar pavement shops. He was doing crazy tennis forehand like movement. My interest was piqued. So I walk up to the guy to get a closer look at this insane action. It was then I realised that the ‘racquet’ is an electic fly killer. As soon as he traps a housefly with the bat, you hear this ‘Bbzzzpptt’ sound of the fly getting electrocuted.
