A B-road walks into a Bar, he orders a pint, sits down, and starts reading the newspaper.
5 minutes later an A road walks into a bar, he orders a pint, sits down, and starts reading the newspaper.
The B-road moves to the opposite side of the bar, peeking frightfully over the top of his newspaper at the larger, higher maintenance A-road.
Later, a motorway walks into a bar, he orders two pints, sits down, and starts to read the newspaper.
The B-road and the A-road both cower in the corner of the bar, scared of the motorway, much larger than themselves and of much higher importance.
Then, a single white line walks into the bar.
Everyone instantly goes up to the barman, attempting to pay their tab, looking immensely worried.
The barman turns to them and says:
"Why are you so scared of him, he's much smaller than you"
The Motorway stuttered and glanced over his shoulder:
"You don't want to get on the wrong side of him, he's....a c-c-c-cyclepath"
