Three women touring London decided to ride a double-decker bus to see the sites. There were only two seats left on the bottom of the bus and only one seat in the top of the bus available when they board. They decided to take turns riding in the top. One of them went up and a couple of hours later it was the next woman’s turn. She walked up the stairs, and saw the first lady sitting there scared half to death – clutching the seat in front of her so hard that her knuckles were white. "What's goin' on?" she asked, "We're having a grand old time down below." The first woman replies, "Yeah, but you've got a driver."
