There are two pieces

There are two pieces of tarmac sitting by the side of the bar, and they are having a drinking contest, to see which one is the hardest.
After 12 shots of vodka, both pieces of tarmac are still unfazed, when suddenly the door opens and a red piece of tarmac walks in.
Upon which seeing the red piece of tarmac, one piece of tarmac runs into the john.
An hour later, he ventures out and discovers that the red piece of tarmac has left, so he ventures out and upon seeing the other piece of tarmac, he is asked why he ran off.
To this he replies ”Haven’t you heard about him?, He’s a CYCLE-PATH !!!!!!”
