In the honeymoon suite, PICKUP the cord that Fawn used earlier.
Leave the suite, go down the elevator, and exit the casino. Hail a cab and go to Lefty's. Head inside. USE the red door to knock, and then USE the password on the eye slot. Go up the stairs and into the hooker's room. USE the window and Larry will climb outside.
WALK left, and Larry will fall off the fire escape into the trash bin. He will automatically pickup the hammer. Time to go back up to the fire escape ... WALK to the left side of the screen — Larry will exit the trash bin and go to the front of Lefty's. Go back inside the bar, USE the password on the red door again, then go back upstairs. Exit the hooker's room through the window again.
On the fire escape, open Larry's INVENTORY. SELECT one of the short cords, and use it on the other short cord. DO NOT use the long cord. Now, SELECT the combined cords, and exit the inventory.
Use the combined cords on the fire escape railing. Now, use the combined cords on Larry.
With both ends of the combined cord tied, use the hammer on the window. Larry will pickup the Spanish Fly pills. Exit the area, and return to the front of Lefty's (either by going through the window, or falling into the trash bin). Hail a cab, and head back to the casino.
In the casino, use the elevator and go up to the 8th floor. You will arrive at the top floor and see a woman behind a security desk. TALK to Faith. You can TALK to her again, but it's not necessary. Give Faith the Spanish Fly pills.
