Jim, a fireman came home from work one day and told Barb, his wife, "You know, we have a wonderful system at the firestation.

Bell 1 rings and we all put on our jackets
Bell 2 rings and we all slide down the poll
Bell 3 rings and we're on the fire truck ready to go.

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 Jim came home from work and yelled, "Bell 1!" Barb promptly took all her clothes off. When Jim yelled, "Bell 2!" Barb jumped into bed. When Jim yelled, "Bell 3!" they began making love.

After a few minutes Barb yelled, "Bell 4!"

"What the hell is Bell 4?" asked Jim.

"Roll out more hose!", Barb replied, "You're nowhere near the fire!!"
