Two strips of asphalt walk into a bar

Two strips of asphalt walk into a bar and start talking about how tough they are: "Trucks can roll over me and I don't even flinch" etc.

Suddenly they both duck under the table when they see a green strip walk in.

After he's left they come back out and the barman says "What the hell was that? I though you guys were tough?"

They say "We are, but that guy's a fucking cycle-path."
