Just as Alice lies down on the bed, an elevated train passes by very close to the window, shaking the room so hard that she's thrown out of the bed.
Thinking this must be a freak occurrence, Alice lies down once more. Again, a train goes by and shakes the room so violently that she's thrown to the floor.
Exasperated, Alice calls the front desk and asks for the manager, who says he'll be right up.
The manager is skeptical, but Alice insists the story is true. "Look.." Alice says, "Lie here on the bed, you'll be thrown right to the floor!" So, the manager lies down next to Alice.
Just then Mike enters the room. "What are you doing here??!!" Mike shouts.
"Would you believe if I say I'm waiting for a train?" the manager calmly replies.
And he was thrown right to the floor by Mike.
