A man and his wife check into a cheap hotel.
The husband goes down to the bar, but his tired wife goes up to the room to lie down.
Suddenly, an elevated train passes by very close to the window, shakes the room and throws her out of bed.
She lies down again, but the same thing happens.
She calls the front desk, and the manager comes up to investigate.
The wife says, “Lie here on the bed, you’ll be thrown right to the floor.”
The manager lies down next to the wife just as her husband walks in.
“What’s going on here?” demands the husband.
The manager replies, “Would you believe I’m waiting for a train?”
