Two pieces of tarmac walk into a pub, one red and one black.
Bar man suddenly looks incredulous and shouts to the red one; ” get out you, you’re barred!” So the red tarmac turns around and leaves the pub. The black tarmac orders his pint, and while the barman serves him, asks “why did you kick him out then?”.
The barman looks up and responds, “don’t you know? He’s a cyclepath!”
