Long one but worth a read

One day, cops were trying to catch a thief who just stole a lady's purse. They were chasing him and all of a sudden lost him in one of the streets.
A guy was walking around the same area, the cops asked him if he had seen the robber. He replied: "There are 4 right turns in this street, don't take the first , don't take the second, don't take the third but take the fourth one.

That lane also consists of 4 rights, don't take the first , don't take the second, don't take the third but take the fourth one.

That lane too consists of 4 rights, don't take the first , don't take the second, don't take the third but take the fourth one.

Once you enter that fourth lane, you'll see 4 buildings, don't enter first , don't enter the second, don't enter the third but enter in the fourth one.

The Building consists of 4 floors, don't enter first , don't enter the second, don't enter the third but enter in the fourth one."

Getting impatient, one of the cops yelled: "And then WHAT!"

The guy replied: " The floor consists of 1 room only. Open that room. It has 4 wardrobes, skip the first, skip the second, skip the third,
open the fourth one, you'll see my mother's picture,
I swear to her that I don't know where the robber is"
(Unfortunately, one of the cops shot him in the dick and spent the rest of the time in prison. The cops did, eventually caught the robber in the fourth floor of the fourth building)
