A scientist invents a drug that makes animals 10 times their size and apart from the obvious profit to be made in meat sales, decides to experiment in other areas. So he makes himself a crude box cart and harnesses it up to a six foot chicken and away he goes. In no time he is on the M1 overtaking traffic - hits 120 mph and the harness gives - big fcuk off chicken is gone and there he is, sitting in the overtaking lane of the M1 between junctions 21 & 22 in a friggin' box cart! Traffic cop pulls up and says 'What the hell do you think you are doing in the overtaking lane of the M1 in a box cart?" "You won't believe this, officer" says the boffin "But my big Hen's gone"
