A man had to attend a large convention in Chicago. On this particular trip he decided to bring his wife. When they arrived at their hotel and were shown to their room, the man said: “You rest here while I register – I’ll be back within an hour.”
The wife lies down on the bed… just then, an elevated train passes by very close to the window and shakes the room so hard she’s thrown out of the bed. Thinking this must be a freak occurrence, she lies down once more. Again a train shakes the room so violently, she’s pitched to the floor.
