Helmets & Lights

Across the bar a piece of tarmac is boasting that, as a piece of the M1, he is the toughest tarmac around.
But, then a piece of green tarmac enters, and the piece of M1 ducks under the bar.
The barman peers over and whispers.
"I though you were the toughest tarmac around"
The peice of M1 answers.
"well yeah, but that guys a cyclepath"

One for me, and one for the road!
