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: we all put on our jackets, BELL 2 rings: we all slide down the pole, BELL 3 rings: we're on the fire truck ready to go.”
"From now on when I say BELL 1, I want you to strip naked. When say BELL 2, I want you to jump in bed. And when I say BELL 3, we are going to make love all night."
The next night he came home from work and yelled, "BELL 1". The wife promptly took all her clothes off.
Then he yelled "BELL 2”, and the wife jumped into bed. Next he yelled "BELL 3", they began making love.
After a few minutes the wife yelled "BELL 4"
"What the hel_l is BELL 4?" asked the husband?
"ROLL OUT MORE HOSE," she replied, "YOU'RE NOWHERE NEAR THE FIRE."
