A man and his wife check into a hotel. The husband wants to have a drink at the bar, but his wife is extremely tired so she decides to go on up to their room to rest.

She lies down on the bed... just then, and 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.

Exasperated, she calls the front desk, asks for the manager. The manager says he'll be right up.

The manager is skeptical but the wife insists the story is true. "Look... lie here on the bed -- you'll be thrown right to the floor!" So he lies down next to the wife.

Just then the husband walks in. "What," he says, "are you doing here!?!"

The manager calmly replies, "Would you believe I'm waiting for a train?"
