A fireman came from work one day and told his wife, "You know, we have a wonderful system at the fire station. Bell 1 rings and we all put on our jackets. Bell 2 rings and we all slide down the pole. Bell 3 rings and we're ready to go on the trucks."
"From now on," he said, "we're going to run this house the same way." "When I say Bell 1, I want you to strip naked. When I say Bell 2, I want you to jump into bed. When I say Bell 3, we're going to make love all night."
The next night the fireman came home from work and yelled, "Bell 1!" and his wife took off her clothes. "Bell 2," and his wife jumped into bed. "Bell 3," and they began to make love. After two minutes his wife yelled, "Bell 4!"
"What the hell is Bell 4?" the husband asks.
"Roll out more hose," she replied, "you're nowhere near the fire!"
