A road crew in new york city was working on a 1 mile stretch of road that they had to close off for repairs and when the supervisor put out the road closed signs and blockades he noticed a hooker a 1/2 mile down the road so he went up to her and said."hey lady we are closing this entire road for repairs"and she said"yeah I know I read that in the paper this morning.So the superviser says"If you know this road is closed why are you working it you arent going to getany customers?Im not working this road im here to learn." "Your here to learn?What are you talking about?" "well the paper said that a road crew is going to come here and start laying payment tonight so I wanted see how that is done so I can add it to my bag of tricks".
I think you flubbed the punchline.
