"From now on when I say BELL 1, I want you to strip naked. When I 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.
When he yelled, "BELL 2!" the wife jumped into bed. When he yelled "BELL 3!" they began making love.
After a few minutes the wife yelled "BELL 4!"
"What the hell is BELL 4?" asked the husband?
"Roll out more hose", she replied, "You’re nowhere near the fire!"
