A dual carriageway walks into a bar, buys a drink and sits down chatting to the barman.

A motorway walks into the bar, buys a drink and also sits down and chats to the barman.

The door swings open and in walks a lane. The lane buys a drink and sits down fiercely.

At this, the dual carriageway and motorway both leave their drinks and rush behind the bar, cowering behind the barman.

"What are you doing asks the Barman?"

To which the motorway replies "Him over there, hes a cyclepath."
