Joke....... 
  A lorry driver is doing the usual 60 mph on the M1, when a Ducati rides up alongside, the rider sticks the throttle open to keep a constant 60mph, then he jumps up onto the saddle and rummages about in his leathers until he pulls out a packet of Benson & Hedges, he then pulls a cigarette out and knocks on the window of the lorry 
 
 " Got a light, mate" asks the biker 
 " Bleedin' 'ell, you'll kill yourself doing that"!!!! says the trucker 
 " Nah" says the biker " I only smoke 3 a day"!!!!!
