The Stench of Honolulu by Jack Handey:
I came to Doctor Ponzari’s laboratory. I started to jimmy the lock on the door, but it was already open. Don’t you feel stupid when that happens? I went inside.
Lying loose on the window seats were clamps and matching curtain rods. I assumed the clamps were used to hold people down while experiments were done on them. I shudder to think what the curtain rods were for.
