A Drunk...

An old man is sitting in a pub, whiling away the hours drinking. Eventually he falls out of his seat and lies on the floor. Two guys see him doing this and, feeling sorry for him, go over, pick him up and ask him where he leaves. He mumbles an address and they start to carry him home.

Every 30 yards or so the stand him up and stop supporting him to see if he is capable of walking and every time he collapses into a pile on the floor.

Eventually they get him home and ring his doorbell. They try to make him stand again and again he collapses. His wife comes to door, look at the two men and then down at her husband.
Oh my God!" she screams, "Where the hell's his wheelchair!?"
