I thought this was funny sixty years ago. I haven't the slightest idea where it came from, I read it in a joke book. This good samaritan was walking home late one night when he came upon this drunk on the sidewalk. Wanting to help, he asked the drunk "do you live here?" "Yep". "Would you like me to help you upstairs?" "Yep". When they got up on the second floor he asked "Is this your floor?" Yep. Then he got to thinking that maybe he didn't want to face the man's irate wife because she may think he was the one who got the man drunk. So, he opened the first door he came to and shoved him through it, then went back downstairs. But lo and behold when he went back outside, there was another drunk. So he asked that drunk "Do you live here?" "Yep". "Would you like me to help you upstairs?" "Yep". So he did and put him in the same door with the first drunk. Then went back downstairs. Where, to his surprize, there was another drunk. So he started over to him. But before he got to him, the drunk staggered over to a policeman and cried "For God's sake, officer, protect me from this man. He's been doing nothing all night long but taking me upstairs and throwing me down the elevator shaft!"
