The fire house

One day a firefighter comes home from work and tells his wife:

“We have a wonderful system at the fire station:

Bell 1 rings, we put on our jackets;

Bell 2 rings, we slide down the pole;

Bell 3 rings, we’re on the trucks.

From now on we will run this house in the same way. 

When I say Bell 1, I want you to get naked. When I say Bell 2, I want you to jump into bed. 

If I say Bell 3, we will make passionate love.”

The next evening the fireman comes home from work and shouts:

“Bell 1!” His wife takes off her clothes.

“Bell 2,” and his wife jumps into bed.

“Bell 3,” and they began to love each other. After two minutes his wife screams:

“Bell 4!” “What is Bell 4?” asks the husband. “More hose,” she replies, “you’re nowhere near the fire!”
