Yuppie and Farmer
 
  A yuppie is driving his Porshe at 90 on the M1, when to his surpise he
  gets overtaken by a farmer in a chariot being pulled by a 10 foot high
  chicken.  "I'm not having this" he says to himself at speeds up to a ton
  and passes said farmer and chicken. Minutes later however the farmer and
  chicken blasts past him again, this time doing 110. Not to be outdone the
  Yuppie toes it and whizzes past the chariot at 120. Just as he was about
  to congratulate himself however the farmer tanks past him yet again at
  150, chicken panting like mad and feathers flying everywhere. Much as he
  tries the yuppie can't match the performance of the chicken chariot and
  gives up, slowing back down to 90 as he watches the farmer disappear into
  the distance. Five minutes later he passes the farmer on the hard
  shoulder, the forks of his chariot high in the air and the giant chicken
  nowhere to be seen. Full of curiosity the yuppie screetches to a halt and
  reverses back towards the stranded farmer. "What happened?" he asked.
  "Big hen's gone" comes the reply.
