A fireman came home 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 truck.
From now on, we're going to run this house 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. He yelled,
"Bell 1!" 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's this Bell 4?" the husband asks.
"More hose," she replies, "you're nowhere near the fire!"
